How to boot UEFI usb drive on Dell XPS 13 L322X

Q: How to boot UEFI usb drive on Dell XPS 13 L322X

Hi All,
Dell update popped up new update. Installed. Shut down. Following the update. The laptop loaded up with (probably coincidence):-
Your PC/Device needs to be repaired
The Boot Configuration Data file is missing some required information.
File: \BCD
Error code: 0xc000000d

Attempting to get the Win 10 usb image to boot in UEFI mode doesn't seem to work. Wasted 3+ hours so far looking for solutions. Why can I not change the boot priority order in the bios? UEFI boot seems to always default to windows boot manager irrespective of any selection made. Am I going to have to remove the drive and repair the boot drive.

Anyone managed to boot from external dvd image successfully?
Is the A10 bios locked/limited? Is there a way to unlock?
Great way to ruin my bank holiday. Wife is moaning :(

Any help/links would be much appreciated.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Check you UEFI setup to make sure the update didn't change the drive mode (AHCI to RAID, etc.). If it did, you'll see that problem.

Hello All,
I have Dell Laptop XPS 13 L322X (Service Tag: CC2YVW1).  I am using a an external Monitor  since the screen is flickering with vertical lines and ghosting colors. I updated the Bios and the video driver, and tried the diagnostic mode (Power on and the D key...et) without success.

I just bought a  new screen compatible replacement but the I cant boot  using the new screen and  am encountering the 8 beeps sound. I tried to boot with the external monitor and using the powering the laptop with the D key, the new laptop screen started to switch colors four times and go back the beeping sound.

I tried also to disconnect the Battery and the Ac power  and to hold down the power to empty the capacitors left stored energy without success.
Thank you in advance for your help,

Hi Saladine, 
Thanks for writing to us. 
Looks to be a DOA (dead on arrival) screen. usually 8 beeps indicate either the problem with screen or with the video card, sometimes both. 
Aren't you getting display on external monitor with the new screen attached. if no, then put back the old LCD again and try. This will give a clear picture if its the new LCD or some other hardware.

I was learning how to use Microsoft WDS to PXE boot a computer over UEFI instead of BIOS.  I got a working system using a Dell PowerEdge r710 and a retail Intel Server Adapter i350-T2.
I then tried to see if I can get any one of our various Dell OptiPlex's to PXE boot over UEFI too but they don't seem to allow their NIC to be visible, just visible in legacy BIOS.  We have OptiPlex 745, 755, 760, 790 and 990's.  The Intel NIC's in the 790 and 990 should definitely be able to allow PXE via UEFI with a firmware update with UEFI+PXE flag set.
Are there plans to enable PXE in UEFI in any of the newish Dell OptiPlex PC's at least?

A:PXE Boot over UEFI not supported on any Dell OptiPlex?

Wanted to edit my own post but I guess I can't.  745's and 755's don't have UEFI "BIOS'" in them.

I own a Dell XPS 13 L322x notebook/laptop computer. I lent it to a nephew, who put a BIOS-lock password, and now he cannot correctly remember it --so the machine will do nothing but ask me for the Password/Unlock key.  (It also gives me an "Unlock key Hint Number", which changes each time I make three bad attempts to enter a Password/Unlock Key. )
I have seen on this forum that occassionally someone with the authority and access to the required tool offers to help via Private Message. 
I know that it is against Dell policy to give personal info such as a service tag or an UNlock Key Hint Number in a public forum like this. SO PLEASE - if you can help me, then private message me and I will return to you the information.  Or, if you prefer, answer me here, publically, and I will private-message you.

I called Dell, but unfortunately I am not the original owner; I bought it some months ago on ebay, completely legitmately. I realize that seems like an odd thing to assert, but it is quite relevant, because Dell said it would only help if i could give the details of the original owner as registerted with Dell. I am certain that I am the legitimate owner, but Dell only has a "transfer of ownership" form, which is useless to me, since I have no way to find the first owner of the laptop.

Hi all,
I bought a Dell L322X laptop off eBay around 8 months ago. Its worked fine till now, with no issues or problems. I recently had the "Plugged in, not charging" issue with the battery; it was fixed with a charger off eBay that wasn't Dell made. I've since ordered a new original Dell charger off Amazon, it worked fine for around 2-3 weeks.
However, the battery has since reduced its capacity on what seems like a weekly basis. First it stopped charging at 78%, and kept on going down by around 2-3% a week. It would charge up to 78%, and then stop and say it would take 4-5 hours to fully charge the battery. Even when left overnight on charge it wouldn't go any higher then 78%. It now stops at 60% but when I hover over the battery icon it displays the "Plugged in, charging" message. I've used the Dell detection program and it says there's no fault with the battery so I'm not sure what the issue is here. Do you think its a battery issue and I need a new one? That's what the local computer shop suspected was wrong but I've read that it may be a software issue with Windows 10, and was wondering whether anyone knows anything that could help me here? I'm a student so need the full capacity without having to charge it every few hours.

Is it possible to turn off and on the touchpad  with a hotkey?

A:Turn on/off touchpad with hotkey for Dell XPS 13 (XPS L322X)

I have a Dell XPS 13 and this has bugged me for a year. I've finally fixed it though, via a registry command line:
To turn the trackpad off, run 
reg add "HKCU\Software\Cypress TrackPad Driver\Device Select" /v EnableTrackPad /t REG_DWORD /d 1 /f
To turn the trackpad on, run 
reg add "HKCU\Software\Cypress TrackPad Driver\Device Select" /v EnableTrackPad /t REG_DWORD /d 0 /f
Note that turning the trackpad off shows a slight delay in it taking effect.
To automate these commands, save each command to a batch file, e.g. turnoff.bat, turnon.bat, then you can run them from either the windows run command (Window key + start typing path to the bat file) or via a short-cut app, like slickrun.

The screen on my xps 13 l322x went black during use, after reboot all i get is a white screen during boot, no dell logo, then a screen full of tiny strips of various shades of colour. I can still log into the OS but cant see anything but stripes. Is this likely to need a new screen,  just a new lcd ribbon cable, or is some part of the motherboard faulty.

A:Dell XPS 13 L322x white/stripey screen

To determine what's at fault, attach an external monitor.  If it displays a good image, the wiring harness or LCD is most likely at fault.
If the external monitors shows the same fault, it's the GPU (and therefore the mainboard needs to be replaced, since the GPU is not a separate component in this model system).

hello guys, I think i had a power surge last night at home and two of my laptops died. My XPS LED lights will go on but fan wont spin and screen stays black. I took it apart, removed cmos battery left it unplugged for like an hour and still no luck with it.
I am guessing that the motherbard has been damaged with a power surge since my other laptop died and has the same exact problem.
Where can i find a replacement motherboard? Can i Install the i7 motherboard even tho my xps came with an i5? Does the heatsink and rest of the parts remain the same between the i5 and i7?

A:Dell XPS 13 L322X i5 need motherboard replacement in europe

You'll have to search for a local source.  The CPU is soldered to the mainboard, so it gets replaced with the board itself.
You can replace an i5 board with an i7.  The only caveat would be that systems having Intel-only GPUs generally use a different heatsink than those with hybrid Intel-nVidia or Intel-AMD GPUs.

Hi all!
I have Alienware Aurora R4 machine with three hard drives:

(Local Disk)C: - (Windows 7) the “original” one that I bought with the computer.
(OS)D: - (Windows 10 with all updates) the one I’ve added after the “original” started to show signs of degradation.
(STORE)F: - (no OS) the one I use just to store stuff.
I’ve had dual boot and everything was hunky-dory until last week the C drive have finally kicked the bucket.
First the computer refused to shut down until I forced it. And next morning it took more than TWO hours to boot. When I finally got to the window explorer the C drive was still there but I couldn’t access or do anything to it.
In the old times I could just remove it and set boot priorities in BIOS to boot from drive D. But if I actually remove the dead drive now, the computer says that it has nothing to boot from. 
It appears that with UEFI mode enabled

I don’t see the actual drives in the BIOS (It only shows general source types, like Hard Drive, CD/DVD, etc.) and therefore cannot boot from a particular internal drive.
I cannot assign Active Partition
I cannot remove the dead C drive

So, what am I supposed to do? Please, HELP!

So, I got a Inspiron 3537 i5. Nice laptop for it's price. Downloaded all the manuals, made my recovery DVDs. All was well in my world.
First thing I noticed is that there is no info in the manuals for tweaking the BIOS and since it is my first experience with a UEFI bios I was a bit disappointed. Is there a manual available for it?
Next I upgraded ATI Drivers to 13.12. I am an old user who always knew that updates were usually a good thing to do. Got in the same problem as many others with PC screen not waking up from sleep.
Thought I would do a recovery from the disk, but after trying various combinations (Ctl+F11, F8, F12 etc) I couldn't find a way to boot in the Recovery console. I did the recovery from my DVD and the laptop works fine.
Does anybody know how to add in UEFI bios a boot option to the Recovery partition? I undersstand that I have to create a new boot option using "Add boot option" and the two options available are to boot to the 1st (windows EFI) or 2nd (recovery partition), but the path for the recovery efi file to be loaded is unknown (+ you can't have access to the recovery partition to see the contents of it from windows). Any suggestions?

A:Inspiron 3537: Boot to Dell recovery UEFI Bios

Still haven't found a bios manual, but anyway. I found a combination of drivers for graphics that does work and allows sleep function without a glitch.
Uninstalled amd (complete), reboot, intall iris, reboot, install latest amd. Ati probably fixed the issue that did not allow wake from sleep. I downloaded them using amdautodetect utility and intel driver update utility.

I recently installed a software on my laptop, but when using it I get the following error message :

Faild to create OpenGL context for format QSurfaceFormat(version 2.0, option QFlags(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1 blueBufferSize -1, alphaBufferSize -1, StencilBufferSize 8, samples -1, swapBehavior 2, swapInterval 1, profile 0).
This is mostly likely caused by not having the necessary graphic drivers installed.
Install a driver providing OpenGL 2.0 or higher, or if this is not possible, make sure the ANGLE Open GL ES 2.0 emulation libraries (libEGL.dll, libGLESv2.dll and d3dcompilet_*.dll) are available in the application executable's directory or in a location listed in PATH.

It is my understanding that I have to install an appropriate driver for my graphic card, but I cannot find which one. I am using Windows 7 (64bits) in a Dell XPS 13 laptop L322x.

Hello all, This is my problem: My BIOS won't boot my USB drive while in Secure Boot mode (Legacy Support disabled). After researching this, I realized UEFI Secure Boot won't read NTFS formatted flash drives hence requiring user to reformat to FAT32. I've reformatted to FAT32 but it still won't boot. I continue to run into the 'Boot Device Not Found. Please install an operating system on your hard disk.' screen. The only way to get the USB drive to boot is to disable Secure Boot and enable Legacy Support. Virtually every forum I have researched pointed to this being the problem (aside from loose hard drives / hard drive and/or memory problems). I have checked the hard drive and have ran the F2 System Diagnostics and am sure there is no problem with the HDD. I have even tested the RAM/CPU with Memtest86 with 0 errors. I have ran multiple 'sfc /scannow' tests after each fresh Windows install and there are no corrupt files during installation. I have been trying to install a fresh Windows 8.1 with Bing (32 bit) on a system that originally came with 64 (there were no 64 bit ISOs available anywhere to download and since Microsoft conveniently doesn't make this specific Windows version available for download via their Media Creation Tool (or anywhere else on their or their affiliate sites for that matter), I was forced to resort to a 3rd party site to obtain this download. The problem is I am forced to install using Legacy Support as there appears to be no o...

HP Notebook 15-f009wm
OS: Windows 8.1 with Bing 32 bit

Hello all,

This is my problem:

I can't get my USB drive to load while in Secure Boot mode and continue running into 'Boot Device Not Found. Please install an operating system on your hard disk' screen. The only method that works thus far is disabling Secure Boot mode and enabling Legacy
Support. Here are the methods I have tried based on extensive research of various forums after several days:

- Performed all the generic System Diagnostic tests (F2) + Memtest86 + sfc /scannow multiple times after every fresh install + physically checked HDD. Performed all HP recommendations: http://support.hp(DOT)com/us-en/document/c01443463

- Did multiple fresh installs of Windows 8.1 with Bing (32 bit) erasing all partitions from hard drive every time (my system is designed for 64 but I only have access to a 32 ISO). Installed using Legacy Support (I understand you can't go back and enable Secure
Boot and disable Legacy once it has been installed this way but due to lack of any other way of installing Windows, I have no choice).

- Used 'Windows 7 USB/DVD Download Tool' to create ISO which automatically formats drive to NTFS; converted to FAT32 using 'AOEMI Partition Assistant' software (preserving all partitions/data) but it still won't read.

- Used 'Rufus v. 2.11.995' software to create ISO as FAT32 under several different setting iterations:

I have a Dell XPS 15 9550 with a Windows/Arch Linux dual boot. I am able to boot Arch Linux using rEFInd but all my attempts to boot it using EFISTUB failed with a kernel panic.
According to this post, the issue is that kernel parameters are not passed by the UEFI implementation at all. Can someone confirm this? Does Dell intend to fix it?

A:Dell UEFI implementation does not support Linux Kernel EFISTUB boot ?

Likely not, since Dell doesn't support Linux on this model.  Where they do support Linux, it's usually Ubuntu.

Hey everybody,
my XPS 13 L322X Sputnik recently stopped working.

When pressing the power button (on AC or on battery), the keyboard backlight turns on and the battery status indicator shows the battery status (blinking read when battery low and white when fully charged)
After a while, a fan spins up but otherwise no beep signal or anything like that can be heard
Neither the BIOS video output can be seen on the Laptops screen, nor the screens backlight. The screens remains perfect dark.
Pressing Fn+F6 doesn't turn the keyboard backlight off nor does any Fn+F* combo do anything perceivable
When i blindly enter my (software) disk decryption passphrase after a while of waiting (just as if only the display died and everything else was working normally), the laptop doesn't appear on the wifi network as it used to do automatically after bootup. 
If i connect an external display to the laptop (which used to be working perfectly with it), no video signal can be seen on the external display

My assumption is that a loose screw  that i found inside the laptop (belonging to the mSata SSD card) after opening it had caused a short circuit and destroyed one component of the laptop. I am out of Dell Complete Care and would like to try a self-repair. Now the big question is: How can i conclude which part to replace?
My findings are few:

A:Dell XPS 13 L322X (early 2013) - no output whatsoever - any hints for self-repair?

You are not hearing any beep codes at all on the system when trying to start it up?   Do you have any mini-Display Port capable monitors you an attach to it to see if the video is seen on an external display?   If no post  is happening, and thus no video to the screen, I would expect there to be diagnostic beeps coming from the system.  
Here is a link to an article on No Power / No Boot troubleshooting that you may find helpful.  You may also want to go to the Dell Support Home page, type in your service tag, and take a look at the diagnostics that are available for that system.  
I'm not sure that replacing the motherboard without confirming that an external monitor isn't receiving video would be what I would recommend.  On the support pages you'll find an owner's manual that will show you how to remove the battery in that system.  Have you tried removing that to see how the system responds?
Let me know what you've found out and I'll see if there are other ideas I can think of to help you.

This is how I got my T5600 to work from a SSD SATA connected to a PERC 310H card and boot as UEFI. It can also be a SAS drive. In this example I was only using a single drive and have not attempted a RAID setup. 

I may have skipped some parts where you have to reboot. If I refer to the BIOS settings then you would have to reboot first. 

1. Setup hard drive as a NON-RAID drive. When booting it will appear as BIOS handled and NON-RAID.
2. Download the Windows 10 installer onto USB using Microsoft Media Tool.
3. Download the DELL T5600 Payload for T5600 and BIOS files (if needed). Install latest DELL BIOS if you have an existing older OS. 
4. Unzip the DELL driver payload onto the USB drive for Windows 10 and leave inside a folder called T5600.
5. Using a rear USB slot that is NOT USB 3. Go into F2 and load the USB stick under UEFI, it may have a strange name if the BIOS is old (such as INT13). Saqve changes. Reboot. Boot from the USB stick. 

6. Make sure the drive you are working on does not contain data you want to keep. Ideally you would disconnect any drive you dont want to accidentally alter. 
When given the option to select a hard drive, if necessary, delete any previous partitions so the drive is without any partitions. Then click the * NEW button. 
7. After clicking NEW it MUST generate 4 partitions, 3 system partitions + 1 OS partition (made by Windows installer). If it only has 2 partitions it will never work as a UEFI boot volume

I would like to boot from UEFI (not bios) using a hard drive on our HP8300 small form factor boxes.  We need to boot from UEFI, because we want Windows 8 bit locker to interact directly with the hardware encryption of our Samsung SED SSDs (840 EVO). No problem loading windows 7 via bios on the Samsung SSD hard drive using the Windows install disk and booting from the CD drive as a legacy (bios) boot source.  This boots the machine using bios- and it recognizes the SSD as a legacy Hard Drive (SATA). BUT-- if I boot from the windows install disk from the UEFI prompt for the CD drive, Windows sees the Samsung SSD but says it can't install to it and can't boot from it.  Also, I notice that there are no hard drive boot sources listed in the HP Setup utility-- just USB hard drive, USB CD, and ATAPI CD.  Are the integrated SATA controllers NOT UEFI boot sources? The Samsung SSD was initially configured as a GPT device-- Windows 7 install (from a UEFI boot) still said it could not install windows to the SSD. Any white papers about HP UEFI?  Anyone know details?

This is somewhat of a follow on to my earlier post dealing with migrating the OS to an SSD.  After havinig cloned the OS from the 2TB HDD, I wanted to boot from the SSD.  In the old days I would have gone to BIOS and from there selected boot priority of the various devices.  In this instance, I encountered UEFI and could not figure out how to change boot priority.  I saw options for legacy boot, some messages about disabling secure boot, and I was afraid to touch either.   So....I just swapped the disk cables and booted from the SSD.  
Still, I have the question, how can I change the boot priority?  Is there some Dell manual that gives a good explanation of the UEFI interface for me to study?

Here is my situation:

I have upgraded a few days ago my daughter's PC from Windows 7 home premium to Windows 10 Home. The upgrade (a clean install) was done on a brand new SSD (Samsung 860 Evo 250gb). After the upgrade, I loaded several programs and created an image of my C: drive with Macrium reflect v7.2 free.

When I installed the Samsung Magician software I realized that AHCI mode was not activated. So I went into the UEFI and turned AHCI mode on. I saved and rebooted the PC. On reboot what I got was a blue screen of death (BSOD). In the process, I lost my Boot manager and had a hard time reboting. Now, everything is screwed up. Sometimes the PC boots and sometimes it does not. It is a mess. It is not reliable at all. When it boots though, everything works normally. Every time, I just do not know if I will be able to reboot or not.

I did not know that I should have enabled the AHCI mode in the BIOS (or UEFI if you prefer) BEFORE installing Windows 10.

To solve the problem, I am thinking of running a restore with Macrium Reflect as I have an image of the boot drive dated the day PRIOR to the day I changed the AHCI mode in the UEFI. BEFORE I restore, I want to change the UEFI setting of AHCI mode to ON.

My question is this:

Question 1
If I do just that, will it save my butt ? I mean not have to re-install everything.

Question 2
Will windows install the necessary drivers for the AHCI mode (after the image is restored) or will it turn AHCI mode back to IDE... Read more

I am planning in the near future to buy a Dell XPS 8910 Special Edition.  I hope shortly after purchase to install a Western Digital Black Series 2-TB hard drive.  This new drive would be used as a storage drive for extra data.  It would NOT replace the original 2-TB drive installed in the system.
From checking the service manual online, I understand how to physically mount the drive, connect the nearby power cable then use my own SATA cable to connect the drive to the motherboard.  I also understand how to use Device Manager in Windows 10 to add/format the new drive.
From other posts I've read here, I must ask: Will I need to enter the setup mode(BIOS/UEFI) at the start of bootup to set the SATA port to detect the new drive, or will the SATA ports automatically detect the new drive without requiring my going into setup mode? 
Thanks in advance to any who can answer my question.  I'm looking forward to getting my new system soon!

Hello, I am trying to switch from BIOS to UEFI, but when I do that I noticed that the hard drive is missing in the UEFI boot options. It does show up in the BIOS options. I also confirmed the hard drive is using GPT. The BIOS version is current as of today. Any ideas?

I have just purchased a Dell Inspiron 17R Special Edition 7720. It came with a preinstalled Windows 8 (so 64-bit and mandatory UEFI boot). I want to use Linux (more specifically, Archlinux) for work and Windows for games, so dual boot is needed.
I almost completed the Linux installation except for the bootloader: I need to boot Linux from UEFI and didn't manage to do it so far. Here is what I did after I received the PC:

disabled Secure Boot;
updated BIOS to version A12 (maybe I shouldn't have...);
resized the main Windows partition and created a few partitions for Linux;
switched to legacy boot mode and managed to boot a MBR-bootable Archlinux installation USB drive;
installed most of the system
switched back to UEFI boot mode, Secure Boot off.

At this time I needed to boot the kernel from UEFI for the bootloader installation program to have mandatory access to the EFI environment variables. So I created an UEFI-bootable Archlinux installation USB drive (with a FAT partition) but so far I couldn't manage to successfully boot this drive from UEFI instead of Windows 8.
I think I really tried every single combination, such as:

different USB ports;
different boot entries created with F2 boot setup, with different parameters;
different orders for the boot entries;
hit my boot entries directly within F12 boot menu.

No matter what, in UEFI mode the system always boots the Windows partition.
Also, I could not find any relevant manual or s... Read more

Try going into Advanced Start-up Options.   Hold Shift key down while doing a RESTART while in Win 8.  This will get you to a page that will have an option called "Other Devices" (going by memory).    Choose it and you will have all the device options like USB. Give it a try first and I am sure there is a simpler way to boot Linus directly later.

Disabling secure boot (although the Secure Boot Status staed "Enabled", so I used the "REset Secure Boot mode" option too...)2. Chaging Optimal OS Setting to disabled in seetings, but still no use3.

Hi, just received my first custom laptop from PC Specialist, UK.

Am unfamiliar with UEFI and want to configure the DVD drive as primary boot for disk imaging etc.
However I can't see it listed in the bootable devices.

PC Specialist doesn't seem to provide any documentation or tutorial on this.

Options in boot devices are
- Samsung SSD (well, that must be what it is..)
- IP4 Realtek PCIe GBE Family controller
- IP6 Realtek PCIe GBE Family controller

Nothing about the DVD drive or USB devices...

(The DVD drive is working)

Do you have secure boot turned on in the BIOS? I know you have to turn this off for USB devices to be seen for booting.

Hi, I have a HP Pavilion 15 n204tx Notebook with Windows 8.1 running. Now I would like to install a SSD by replacing the optical drive. I am not an expert and I did some digging. I heard that before I install Windows to the new SSD, I should change settings in BIOS to AHCI concerning my hard drive. My Problem now is that I can't find it in BIOS. Where can it be found and maybe changed? Is it really needed to change BIOS mode? What are my alternate choices?

Context of the problem
Laptop model: L322XBIOS version: A08
I seem to be having virtually the exact same issue as this one.  
Except I am on A08.  
Basically the laptop will not boot, I cannot even get into the bios because it never boots to the dell logo.  It started happening maybe a week ago, but after a few trials normally it would work again and boot into windows.  At this point though it will not boot at all.
I have tried his solution at the bottom of the page, but after 30 plus trials it still will not update the firmware to A09.
I am currently completely unable to boot to the dell logo, or windows, every time it tries to start it hangs with the keyboard lit up, and the screen fully black.  I can boot to the dos bios update utility as he explains in his post, but again it will not update the firmware ever.  Any idea what I should do?
Is there anyway I can force it to boot into the bios so I can try to change some settings?  I looked but could not find any jumpers in the documentation for resetting the bios.  

Any help would be greatly appreciated.  Thanks.

**** You need to enable Legacy MBR by Enabling Launch CSM in the EFI Setup ****

Hello all,

This is my first post. I am a Windows 7 user and now (against my will) Windows 8.

I bought an ASUS N76 laptop pre-loaded with Windows 8 so these are the new generation n76 series. The old ones come with Windows 7. Anyway...

I attempted to boot a Windows 7 ULT 64 install DVD but the install hangs on the Windows logo/flag. So...

- Windows is loading files is shown and hidden
- The animated Windows logo appears and then it just hangs....go figure

I have no idea what is going wrong. I went into the UEFI setup and the only option for my BR is EUFI boot.

I also added a "boot option" asking the EFI to boot "efi\microsoft\boot\boot.efi" or "\efi\microsoft\boot\boot.efi" but when selected (from Boot Override), the screen goes blank for a few seconds, the BR starts spinning and I am thrown back at the EFI so it looks like it cannot find the file. For path, I selected the BR device and at the end has a "\".

I have secure boot disabled. (yep, I have an option for that). So now I am left empty handed and I am stuck with Windows 8. I even put in a brand new SSD hoping I would install W7 on it but I can't even start the setup!! Argh....

I am very experienced with MBR and BIOS but I am a complete newbie to UEFI. I don't know what is going wrong and why the setup hangs....Ther... Read more

Trying to understand handshaking between UEFI & Win 7. Have Win7 Pro sp1 64 installed on SSD, mb=Asus F2A85-V Pro. Example: boot to flashdrive to do Acronis backup of SSD; remove SDD, insert spinner; boot again to flashdrive to do Acronis restore to spinner (to test backup); remove flashdrive, boot to UEFI, set UEFI spinner as default, save & reset; spinner starts boot (#1), Win logo shows briefly, reboots (#2) and shows Win repair/normal screen; choose normal; Windows desktop shows; new driver is loaded for spinner and asks for reboot (that part I understand); reboot (#3) starts and again briefly shows Win logo before yet again rebooting (#4) to the Win repair/normal screen; again choose normal & all is happy. But then I remove the spinner, insert the SSD, and have to go through the whole deal again. Why so many reboots?

Similarly, if I change any hd/flashdrive configuration, my UEFI boot selection is lost & I have to reset it again - sometimes with the multiple reboot scenerio, sometimes not. Sure wish I could force that the UEFI selection stay there as long as the selected drive is installed.

A:UEFI boot keeps changing; UEFI/Win7 handshaking confusion

Hello and welcome diana look I am having a little difficulty in following the train of the thread.

Now do you mean you just backed up the SSD to a USB stick ? then tried to transfer that USB stick back up to the spinner? If it was just a back up then I don't think it is going to work because it is only a backup.

To make the spinner the boot device I would be cloning the SSD to the spinner. I wouldn't mucking around with sticks as I cannot see why that is necessary.

Is possible to combine the systems in dual boot and both in UEFI mode?

I see from your guides that for installation the UEFI is necessary partition in a certain way.
What should I do if I want to leave intact the UEFI partition of win 8 (5 partition)? I just make only space for win7(1 partition) that will use the same 4 partition UEFI of win 8 or i make other 5 partition???
And which of the two systems will handle the boot? I can decide I?

Yes. This is how I do any OS tests\'dual boot'\experiments etc with zero chance of damage to the original boot OS\hd. Am keeping a bunch of old HD's for the purpose. The downside is the slight risk for some mechanic\connection problems, just be careful, remember to power down! So if you don't find it troublesome to switch HD's, IMO go ahead and try that route.

Hi all,

Currently having a wake on lan issue with a certain computer.

The machine is setup correctly but the windows boot information is stored in a 100mb UEFI partition, and when the computer wakes on lan, it will not boot windows, just sit at a blank screen.

When it wakes on lan it is trying to boot from the legacy device (same blank screen happens if you choose to boot from it from bios)

ive tried updating the bios but no luck, all settings seem to be as they should be.

Is there some trick to get it to load the UEFI MBR, or is there a safe way other then reformatting the machine to move the MBR over to the legacy device itself?

Thanks for any help.

A:Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup to enable Legacy BIOS. Next check BIOS Boot order for an EFI Boot Disk: remove it, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed here.

At first installer screen Press Shift + F10 to open a Command Box, type:

SEL DIS 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

Next click Install Now to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

Hello everyone
I am trying to make Windows 10 scripted installation with UEFI boot.
Every things works with normal Legacy mode in our environment and k2000.
I have made WINPE 10 boot file as a normal procedure with k2000 Media Manager (like in legacy mode). And uploaded it to k2000. Of cause I have re-cached my drivers when making new a boot source. 
I have setup our new DHCP so it can boot with UEFI and it works!, and I can see my boot sources when boot up the client in UEFI mode. 
Here comes the tricky part I can choose my newly created Windows 10 boot source with Dell's own WINPE10 drivers. Then it loads the Boot source file that I created but It stop at the Windows 10 logo it never loads the deployment menu like in legacy mode, so I cannot deploy a scripted installation.
I am stuck what could be wrong or what have I missed ? Please help

Dear Friends,

Long time reader of this forum but a first time poster, so please forgive me if this question has already been asked and answered.

Laptop: ASUS UX31A-DB71, latest BIOS: 218

Originally my laptop came with Windows 7 and when i looked at disk management my disks were formatted with UEFI schema. One of my friend gave me a UEFI bootable USB drive loaded with Windows 8. So, i thought why not give it a try. So, I created a backup of my OEM Windows 7 and saved the iso files in a seperate external HD (created twice just to be sure . Now, i decided to load the Windows 8. Booted into the BIOS and there is an option to select the USB drive along with the UEFI option for that USB drive. I selected the UEFI option but some reason it does not boot into UEFI. So i decided to select the standard USB install and this option let me install windows 8. In the process of installing i formatted the partitions and made a single partition and installed Windows 8 on it. I am guessing now the drive is not GPT but MBR. I also noticed that his installation USB disk had an option to select either 32bit or 64bit of Windows 8...I find this kind of odd. Would Microsoft create a same iso file with both versions? I am guessing he created the USB from a illegitimate source.
I am planning on purchasing Windows 8 Pro version as an iso but wanted to be confident that it would work with UEFI architecture.

I am in the process of doing a number of clean installs. I am trying to make a decision as to whether or not to utilize the UEFI and Secure Boot modes which are available on the MBs.

It seems from an initial attempt, that I cannot simply use UEFI/GPT without turning on Secure Boot...that is one must NOT use CSM (turn it off) and USE Secure Boot. You cannot use UEFI without Secure Boot.

Is this correct? I am considering us9ng UEFI without Secure Boot because I hear it is faster.

However, I am concerned that I will run into all sorts of trouble turning Secure Boot on with respect to double booting Win 10...and additionally with creating images with Acronis.

I have been in the habit of creating a new PC with an extra drive with a cloned OS...then disconnecting the drive so that if the first OS drive fails, the person can boot up quickly with the other drive. I am concerned that there will be a problem with Secure Boot.

I mean, how many times have I been infected with a root kit.....some virus that take over at boot time...Answer...never since I started with PCs in 1991!

So, anyone really think Secure Boot is worth it?

It is a very important security feature.

Microsoft designed Secure Boot to protect the computer from low-level exploits and rootkits and bootloaders. A security process shared between the operating system and Unified Extensible Firmware Interface (UEFI, replacing the BIOS), Secure Boot requires all the applications that are running during the booting process to be pre-signed with valid digital certificates. This way, the system knows all the files being loaded before Windows 8 loads and gets to the login screen have not been tampered with.

If a bootloader has infected your computer and it tries to load during the boot-up sequence, Secure Boot will be able to undo all the changes and thwart the ... Read more

Hi, I just bought a Dell XPS 8500 a few months ago and recently wanted to do a clean install of Windows 8.  I have two Windows 8 USB drives.  One is a Windows 8 Pro that I bought and the other is a Windows 8 standard that came from Dell.

I only have one MSATA SSD drive installed in the machine.

When I try to do a clean install, all the steps works fine.  It proceeds fine to the last step where it copies all the files.  Then, it will give me a 10 second count down timer and restart the machine.  After the restart, I get the following error message:

The computer restarted unexpectedly or encountered an unexpected error.  Windows installation cannot proceed.  To install Windows, click "OK" to restart the computer, and then restart the installation.
When I click OK, the computer restarts itself and I get the same error message again.  It's like an infinite boot loop.  I have also tried the following:

Install Windows 8 Pro upgrade USB drive, same results
Install Windows 8 standard Dell USB drive, same results
Install Windows 8 standard Dell DVD ROM drive, same results

I've also tried all of the steps above with a 300gb SATA HDD that I have.  Unfortunately, same results.  I've also completely powered down the system and waited about 20 seconds.  When it starts up, it gives me the same error message again.

Hi funkmasterta,
I will suggest you to check the BIOS settings provided below to see if you have similar settings. If not you may try these settings and then install the operating system.

Go to the BIOS screen by pressing F2 at the Dell logo 4-5 times.
Navigate to ‘Advanced Tab’ and select ‘Onboard Device Configuration’.
Set ‘SATA Mode’ to ‘AHCI’.
Navigate to ‘Boot’ tab and set ‘Secure Boot’ to ‘Enable’ and ‘Load Legacy OPROM’ to ‘Disable’.
Boot Mode should be set to ‘UEFI’.
Save the settings and Exit from the BIOS.

Once the system restarts, Go to the ‘One Time Boot Menu’ by pressing F12 at the Dell logo 6-7 times.
Select the boot device under UEFI to boot.
Keep me posted with the results. I will be glad to assist you further.
