Preferred Solution: Re: Elitedesk 800 G3, WIndows 7 and UEFI network/pxe boot

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.)


UEFI PXE boot dont seem to be working in CSM mode.Has anyone got UEFI PXE to work with WIndows 7 on these models?

I'm trying to change our boot configuration from BIOS to UEFI. I've tried to simplify the problem. I'm booting via BIOS PXE to SCCM task sequence and performing following actions:Apply UEFI Secure Boot configuration with BiosConfigUtility (Secure Boot enable, boot order that is ignored anyway...)Set disk partition type as GPTCreate Fat32 partition for EFI boot and NTFS volume for dataApply WinPE to NTFS and copy boot files (bcdboot) to Fat32Set Fat32 volume as ESPRebootNow BIOS will not allow me to boot this disk. Disk shows up in "Device configuration" but not in Boot order.If I boot again to PXE (now in UEFI mode) and check disk contents, all seems in order. If I reapply my script to redo steps 4 and 5 then on following boot the disk will apper in Boot Order and boot.If before first UEFI attempt I put in a known UEFI bootable disk, the system will not boot it either. I'm thinking that there's a bug in BIOS. I've seen something similar with Z620. When applying some config changes to BIOS, system will no longer show valid boot hard drives in Boot Order (that attempt was in BIOS mode). Switching controller emulation to RAID and back to AHCI worked around it then. But this time I'm not changing controller emulation. Also BiosConfigUtility reports that it has set boot order changes but when reading them back (before or after reboot, they're the same). That's not as important but BiosConfigUtility v2.68

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

If your computer was running WIndows 10 without any issues prior to downloading the Anniversary update, then you would not have had to change any settings in the bios to install the update.The UEFI and Secure Boot settings are to enable booting with a USB or DVD to install Windows.
Disable Legacy Boot Mode and Enable UEFI
Start the computer and TAP the F2 key to enter the bios. Once in the bios Press F9 to Restore the bios to the Default Settings. F10 to save changes and exit. You could have a hardware problem.

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.

Hi , I have some Lenovo ThinkCentre M91p dekstops which I try to boot over our network in uefi pxe boot but no luck so far. Our pxe network server is setup to work with uefi only so I set m91p in bios to uefi mode and tryed to boot over pxe but I think network is still in legacy mode, with other type of boot option I have two options to boot ( for example usb flash drive - legacy and uefi boot in submenu to choose in auto bios mode , in uefi bios mode it boot directly in uefi the usb flash drive ) but for the pxe boot its the same in uefi bios option and auto/legacy - connects to network pxe , try to boot and same error for too big size like we get if bios is set to legacy ot cms mode. So my question is it possible to boot in uefi pxe mode this desktop ? Or we will need to change pxe server to allow and working with legacy.Thank you for your answers.

Hi, I want to deploy an image on the HP Z2 Mini G3 Workstation. We do this with Windows Deployment Service. But, if I want this to work, I need to boot via UEFI Network, but I can't find that option. The only option I see is Legacy. When I choose Legacy Network boot, it won't show the SSD to install Windows on. I've seen this behaviour before on different HP-devices, the solution then was to network boot via UEFI. Yes, UEFI Boot Order is checked, Legacy boot is disabled. Secure Boot is also turned off. The only two boot options I see when I go to 'Boot Menu' are the SSD and an USB-device. How do I get this UEFI Network boot option?

When searching verifying the correct version for my BIOS update I ran into an insidious website that rather than providing me any type of info of a potential updat rather provided me with redirects, PUP's and all types of junk that was challenging to rid the computer of.
After I found the correct version to update my BIOS I flashed the download and the BIOS is now updated correctly.

I don't know exactly if the attack is still pestering my system or I may be dealing with something else Point being if this is in the wrong Forum category I apologize in advance.

This is stats as to my Acer Aspire Es-711.

The issue I'm having is that when I Configure the BIOS such that the computer will search for the Hard Drive (C:\) I get an obtrusive message stating that there is no bootable device found.
This is using the UEIF and Hard drive configuration.
I get this message directly after booting the machine in this configuration.
This would lead one to think that there was an issue with the HDD and that one would follow that
Rabbit hole (as I did ) for a resolution.

What I learned in researching this is that when setting the BIOS to boot to the USB/CD/DVD The machine that happily takes me to a screen asking me to push the "any key" to load the Windows Program.
My immediate thought when this first came up was it was absurd as the computer was not able to find the bootable device.

**** 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....

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.

After creating a UEFI bootable USB thumb drive with Rufus (using Windows 8.1 Enterprise ISO x64), for a Dell Optiplex 3010 (configured as UEFI only, no CSM, latest firmware version, Windows 8 installed), I didn't see a USB boot option, so I tried to add one manually. Unfortunately I erased the existing boot option (boot manager) by mistake. Although there were two boot options for PXE booting, the machine will not start anymore, even when there is an active WDS server on the network.

I also see Led's 2 and 3 lighting up, meaning according to the manual 'hardware ok but bios possibly damaged/corrupt'.

I understand I cannot start the machine from a bios boot disk because of GPT partitioning, and the UEFI USB boot disk I made might be corrupt (as it didn't show up as a boot option), however I don't understand why it won't boot from the PXE network card, as these boot options are still there.

Any suggestions on how to solve this?

Thanks for any useful tips,

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.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

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.

I have a new Precision 7710 with a 2.5 inch 1GB SATA SSD (system boot=Disk0) and a 1GB NVMe PM951 SSD.
I have been attempting to install Windows Server 2012R2 on the second, M.2 SSD (Disk1) into a GPT, NTFS partition.
Since this system has no DVD, I made a bootable UEFI thumb drive with the contents of the .iso installation for Server 2012R2.
The thumb drive boots OK and I can begin installation, but when it comes to choosing the target for installation, the M.2 SSD is not visible in setup.
The M.2 drive is clearly visible inside Windows 10 Pro as the D: drive.
So...I mounted the .iso setup file in Windows 10 and ran setup.exe. The install began and could see the target M.2 drive, and began loading files on the second SSD. It then attempted the first of several restarts that come with this process with the new Server 2012 R2 environment.
It sucessfully modified the Windows Boot Manager before the restart, then restarted, and the setup program gave an error because it could not find the target partition on the second SSD.
The setup environment then modified the Boot Manager to "Windows Setup Rollback" and proceeded to enter an infinite loop, attempting to delete files from the unreachable M.2 drive. I manually choose Windows 10 on the boot menu, and once booted changed Windows 10 back to the default OS.

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

Since I dont have anything to boot from on my home network the attempt fails.

My HP's power button blinks 5 times and then pauses which, according to the manual, indicates a system board issue.Here's what happened. A friend gave another friend 2 ram memory sticks and my friend had tried to plug it in without powering off the PC. At first the computer did load up and the memory wasn't recognized by the motherboard so we'd shutdown the computer and move the ram sticks around. Nothing worked. On our 5th try the computer stopped booting up. It would power on but the button would flash red 5 times and pause two seconds, indicating a system board issue. This is what we've tried to do so far: reseat the ram; reset the CMOS battery; unseat all the connections on the motherboard to remove any static electricity; and reset all the component connections to the power supply. Nothing worked. Before I tell my friend that his motherboard is fried, is there anything else I can do to get the computer to boot up?

Here what I have tried so far: - Reset the cmos by pressing the reset button (center of mainboard) for 5 seconds without power cord connected- Remove display adaptor and use motherboard display connector- disconnect the hard drive and DVD SATA cables- Remove half of the RAM chips from sockets Nothing helps, screen stays blank. This machine worked a week ago but it started to be "slow" on it's boot. It could takes minutes before it started to windows. But worked normally when it finally did. Is this totally brick or is there something I could try? Machine details:HP Elitedesk 800 G1 SFFs/n CZC44770QXproduct: C8N26AV All help is welcome!Tajuro

Turned out that this PC still has warranty. So please do not spend time to figure this out unless you know it already  Tajuro

The problem is a freeze during Windows 7 64 bit installation loading disk.sys when booting in UEFI mode.

According to Intel online support (https://communities.intel.com/message/206067) :
+"Windows 7 Setup has a problem detecting Toshiba SSD"+

*Disk Drive ATA TOSHIBA THNSNH25 SCSI Disk Device (238 GB)*

Is there anything to do that would make Windows 7 setup loader work with the SSD drive ?

A:Windows 7 freeze after UEFI boot because of SSD

I read the discussion on the Intel community page.
It looks like you already tried all possible solutions to install Win 7.
It looks like Win 8 can be installed properly but only Win 7 isn?t possible.
Not quite sure why this isn?t possible but in case its SSD drive issue, you should try another SSD drive.
Maybe its a compatibility problem between the controller and SSD drive.

I have very little experience with Windows 8 until now. I am having an issue trying to run System Refresh or System Restore from the System Recovery Environment booted from the Windows disc. When I try to run it from the disc I already System Refresh says that the drive is locked. I tried System Restore and it said no OS's were found. I went into the CMD prompt and went to c: and can see the drive just fine.

Steps tried:
running fixboot, fixmbr, rebuildbcd commands from CMDrunning dskchk /f (which forced a dismount)

I then read something about a non UEFI bootable disk couldn't access a GPT partition, which I think is the case here. So then I tried oscdimg to make my iso UEFI bootable (twice) and the UEFI Boot Manager still only shows 'Windows Boot Manager' at the boot menu. I even tried downloading an iso that was already UEFI incase I did it wrong and it still doesn't see it.

Not sure what I'm doing wrong here??

A:Trying to Understand UEFI and how to boot from Windows DVD

When you go to your BIOS boot options the DVD drive should be listed twice, once with UEFI in front of it and one entry with no UEFI in the description. Selecting the entry with UEFI in the description will boot from the DVD in UEFI mode. If the PC doesn't have UEFI or UEFI is disabled you won't see UEFI mentioned in the boot menu.

The screen shot in step 4 here, UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with will show what I mean.

Hey all,

I just got a new HP ENVY dv7t-7200 CTO Quad that came pre-loaded with Windows 8. I wanted to install Windows 7 so I enabled "Legacy Support" in the BIOS which disabled UEFI mode. Everything went fine from there. I ultimately decided to go back to Windows 8.
I found this guide but could not get my Windows 8 installation that I have on disc to load on startup: UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with
I disabled "Legacy Support" in the BIOS so now UEFI mode is re-activated.
My UEFI Boot Order in the BIOS is:
USB Drive
OS Boot Manager

But when I have the disc in and restart windows, it does not read the Windows 8 installation from the disc. If I press F9 to change the Boot Order it only shows:
OS Boot Manager
Boot from EFI File

It should be noted that the it will recognize the disc if I'm not booting in UEFI mode.

I could install Windows 8 again without UEFI but I would really prefer it. Any suggestions?

I have my laptop since last december (less than a year), and for unknown reasons, I got a BSOD a few weeks ago and none of the available recovery tools managed to bring me back to my desktop; not even a refresh. That's when I promised myself that I would never ever again install a Microsoft OS, and went for Ubuntu 16.04 (which was already there on another partition). Now I'm realizing that I need some softwares that work best on Windows and not through a VM (eventhough I already have Windows 10 running in VM for Microsoft Office).

So here's my issue:

I created my bootable Windows 10 installation USB but I can't boot from it! I doesn't even show as an option. Ubuntu does. I tried a USB 3.0, 2.0, UEFI, Legacy, MBR, GPT... Nothing seems to work. Searched forums for hours and couldn't find a solution.

Now for grub to be able to launch at startup, I had to add an efi file to the trusted uefi file list in the BIOS. I was wondering if such a file should be added to be able to boot from my USB... (secure boot is disabled).

I want to keep my Ubuntu and Kali...

I've attached a screenshot of my ssd partitions.

Any idea?

I have set up a dual UEFI boot with windows 7 and WDP every thing is working as it should be but I have one question about the Boot manager.

When I boot my system WDP boots automatically until it is just before the logon screen, at this point I get the Boot manager coming up with the choice of operating system. This is ok If I want to use WDP which is the primary system but it is annoying if I want to select Windows 7.

Selecting Windows 7 causes the system to reboot and start in Windows 7. This is even more annoying if I am using WDP and want to switch to Windows 7 as I have to reboot to the Boot screen and then reboot again to Windows 7.

Does anyone know if it is possible to make a change to the boot manager so that it comes up before WDP boots?
If I was to change to the Windows 7 boot manager would it work the same as WDP? (assuming the Windows 7 Boot manager will see WDP)

A:Windows boot manager under UEFI

I have a Dell Precision Tower 5810 running Windows 8.1 Pro 64-bit
I created Rescue Media for the Macrium Reflect Free Imaging Software on a USB Flash Drive.
I can boot to that USB Flash Drive IF I can first boot into Windows 8.1 Pro 64-bit
But, the chances are that when I will need that Rescue Media, I probably will not be able to boot into Windows 8.1 Pro 64-bit.
I have tried to directly access the UEFI by pressing the F2 key at the Dell Logo after powering on the System.  I also tried F12.  Neither has worked.
Is there something different that needs to be done on a Dell Precision Tower 5810 running Windows 8.1 Pro 64-bit to directly access the UEFI & change the boot sequence when I cannot boot into Windows?

I accidentally deleted the Windows 7 boot entry in the Windows Boot Manager. My laptop uses UEFI instead of BIOS. The OS is Windows 7 64bit Home Premium.

Here what I tried and its results:
Use startup repair: I tried to use Startup Repair from a Windows 7 Installation Disk (actually, a USB). However, it said that the Recovery Options was not compatible. There are many causes as mentioned in Causes of incompatibility and I was able to eliminate these:64-bit Installation Disk: Checked

CPU and OS architecture are the same: Processor (CPU?) Architecture is AMD64, OS is Windows_NT (don't know if the same or not)

Many suggest to use startup repair but I don't know how to make this work.
Use bootrec following Repair Windows 8 efi bootloader: three commands finished succesfully but I still doesn't see the Windows 7 boot entry in the Windows Boot Manager.

A:Repair Windows 7 boot menu on UEFI

Lets start with the basic stuff first. In your bios, there should be a Windows Boot Manager listed in the Boot options. Is that set to first priority? USB flash drives need additional steps to make them useable in UEFI. The Windows USB maker will not work. Use an Install DVD if you have one, if not, download one from here.


If you need to boot to the UEFI version of the Install DVD, you also need to go into the bios and select the UEFI DVD entry.

I will go through your post after this response, so let us know if you are able to run the Startup Repair, if needed.

What motherboard/system do you have?

Edit: EasyBCD is not UEFI aware. It may be able to repair some things, but I don't recommend using it, but since you say a beta does, I will do some testing.

Ubuntu has UEFI also and installs fine using it. No need to use some additional procedure to add it to the boot. Just use the Boot Menu F key to choose it from the list, or go into the Bios to set it first priority. The Boot Device list menu in a one time choice, and does not set that device to first priority in the bios.

I'm trying to Install Windows 10 on my Windows 8 Ideapad Z710, and I can't get my laptop to boot from DVD. From the InsydeH20 Setup Utility, I've so far disabled Secure Boot, set Boot Mode to UEFI. In this case there is only three options 1) EFI Network 0 for IPv4, 2) EFI Network 0 for IPv6, then 3) Windows Boot Manager (no other options). When I boot with these settings  it boots to Windows. Why can't I boot from DVD? Note that when setting is Boot Mode to Legacy Support and Boot Priority to Legacy First (with Secure Boot disabled) which results in this error: "windows cannot be installed on this disk. The selected disk is of the GPT partition style."

I purchased Lenovo Z500 with Windows 8 installed on it. When Windows 10 upgrade started rolling out, I moved to Windows 10 Home.I have been running into some issues with my activation so had been trying to reset to factory default but that is also not happening.I created a Windows 10 UEFI bootable disk and went to the BIOS to set the USB as the first bootable disk in the list but it doesn't show up there.Now it did show up earlier (without me changing any setting in BIOS) when I was trying to do recovery using System Image Recovery option with Recovery Image in the USB. Anyways, now I'm trying to install the Windows 10 from scratch and then Ubuntu 16.x alongside Win10 however stuck at this very phase.I read quite a lot about UEFI and Secure boot and see that in my Boot menu UEFI is enabled and Secure Boot is disabled. Please refer the screenshots.Can someone explain me in detail that with this setting in BIOS what could be going wrong with my steps where UEFI bootable USB is not detected?Also, in addition to that if someone can point me to the latest document/discussion for Dual Boot with Windows 10 and Ubuntu. I might have it bookmarked but just in case.I would appreciate quick and detailed response.Thank you in advance.

Hi all,

I have just recently installed Windows 7 on the Plextor M6 Pro 128GB SSD. Everything went fine for the first few boots, and Windows will not boot up after that. The computer automatically goes into UEFI BIOS as if there is no Windows installed on any of the hard disks.

I removed the SSD and inserted it into the external enclosure and hook it up to my laptop via USB. Windows (on my laptop) did not show any removable media under My Computer. Upon firing up Disk Management, the following screenshot (Screen1.jpg) can be seen.

I humbly seek for advices of anyone out there who might be able to help me regarding this issue. I have previously successfully installed Windows 7 on all my older PC/Laptops. But this is the first time I have installed it on an SSD. My previous installation on HDD works well without issue (used it for 6 months before I reinstalled it onto the SSD). I ran into this issue twice within the same day (I reformatted and reinstalled Windows after my first encouter).

I will post whatever details required to solve the above issue. Also, any explanation and information regarding the issue as well as how to prevent it from coming back would be very useful.

Many thanks in advance!!

A:HELP!! Windows 7 on SSD failed to boot, goes into UEFI BIOS.

Hi there

In all cases ensure LEGACY BOOT is enabled if that option exists in BIOS.

1) First ensure PROTECTED BOOT is DISABLED -- this doesn't mean turning off UEFI.
2) Ensure the SSD is formatted to GPT and NOT MBR
3) Ensure your W7 install media will handle UEFI boot and install.

If you Don't want to use UEFI boot

1) Disable UEFI in BIOS.
2) Format SSD as MBR
3) Install W7 - default mode will be non UEFI.
