UEFI Network Boot options missing on 7450 with BIOS A13

Q: UEFI Network Boot options missing on 7450 with BIOS A13

After upgrading a lattitude 7450 laptop to the latest BIOS, A13, both the IPv4 and IPv6 boot loader are missing when wanting to perfrom a UEFI network boot, Encountered this on all 7450 with BIOS A13. The enable UEFI network stack check box is checked as it was. Any idea where these options went? It is not possible to perfrom UEFI network boot anymore we wanting to reimage it.
The only solution we found around it is to downgrade the BIOS to A12, and then they are back.
Is this a miss from Dell? Cant image they did this on purpose.
Thanks.

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.)

Dear Bleepers,
 
this is our strange situation:
My friend has a samsung laptop Ativ Book 2 (np270e4e) with windows 8.
After few problems when updating to 8.1 (it deleted the o.s and gived only a bsod saying that there is not any os installed), she decided to buy and install windows 7 so she disabled the uefi, setted the legacy mode and the boot priority first to the usb hdd (we have a bootable iso).
Parphaps every time we restat doesn't boot from the disk but showed the windows 8 bsod. Naturally the f4 for restore gives anoter bsod for not founding any partitions!
We discovered that it's not possible to boot from the disk, so we made a bootable usb driver with the official iso.
After that we picked up the hard disk and delete all partition from another pc and disabled all the boot driver but the usb hdd. After that it booted from the pen drive with official w7 iso.
The installation was completed in about 30 minutes. We started to install the drivers, chipset, intel storage but:
the next reboot it showed this message: all boot options are tried. press f4 key to recover with factory image using recovery or any other keys for next boot loop iteration and it was a continue loop and can't access the bios.
Strangely when the usb driver with the official w7 iso was inserted it said: "press any button for starting with usb driver"  and if we don't press anything windows started normally.
So we tried to install another time thinking it was a driver conflict but the second ti... Read more

A:All boot options are tried, no (uefi) Bios

Seems to be a common problem with Samsungs. See this thread and the post by François.  Can you access the boot menu by tapping F2 instead of holding it down? See if you can access the computer with Fatdog64. You will need to burn the iso file or use Rufus to create a bootable USB. If the USB does not boot then use GPT as a partition scheme in Rufus. 
 
According to here F2 is the boot menu for a Ativ Book 2, 8, 9 but F10 is the UEFI access key. Try tapping F10 at boot.

Hello,
I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

Hi,
Recently installed the A23 BIOS and notice under BIOS Settings-> General -> Boot Sequence, there is now support for UEFI. My question is about he setup options available for UEFI. There is 3 settings;
1. Boot Option Name
2. File System List
3. File Name
1 and 3 are obvious. I'm after more information about 2 (File System List). Whats are the various parmeters etc... mean so i can setup an entry for UEFI Bootable USB keys.
I notice when I enabled UEFI, then rebooted and pressed F12 (for boot menu) and automatic entry was generated for the CD/DVD drive but not one for a USB Key. I understood the UEFI Boot options where automatically generated depending on the USB and/or DVD/CD connected and if it find a boot.efi file. I did have a USB drive connected with a boot.efi (a windows 7 install DVD) but it didn't recognise it. So I'm after details to create my own entry.
Look forward to your response.

hi lubeats,
 
Welcome to the Forums.
 
Are you referring to the hidden additional options in the BIOS (like in this image)? AFAIK there are no special combination keys to do this and these options can only be unlocked if you flash a modified version of the BIOS (which, unfortunately, is not officialy supported).
 
For backing up your current BIOS, check this article.

Hey everyone, me again.

Can someone explain to me the different options that are available in UEFI?
I am attempting to do a complete reinstall on Win 8.1, and I want to make sure ALL old files are gone, everything wiped clean and get a good, fresh, start. I don't want to mess anything up after installation by installing the wrong drivers, malware programs, etc., and leave my laptop vulverable as I did the last time.

I'm running a Dell Inspiron3521 (late 2012), pre-installed with Win 8, upgraded to 8.1. I have a bunch of corrupt files, damaged files/partitions, (and not able to run DISM without error codes), among some registry issues. At this moment, I DO have internet access on the laptop. BUT, it will not let me download anything, cmd prompt is not working properly, or will not let me run sfc /scannow or DISM /online.....etc. ..

A:UEFI Boot Options for Reinstall of WIN 8 using USB

How to download and clean install Windows 8.1 if you have an OEM computer with UEFI firmware (BIOS) embedded Windows 8/8.1 product key. -> link






Normally, you do not need to change the UEFI firmware (BIOS) settings, for example, the boot order of drives, enable Legacy BIOS boot mode, enable Compatibility Support Module (CSM), or disable Secure Boot. So, do not change the UEFI firmware (BIOS) settings.

- Connect your Windows 8.1 USB flash drive or insert your Windows 8.1 DVD.
- Restart the computer.
- Press the correct key to enter the boot menu (see this link for help). Or, if you have a Lenovo computer, you can also press the NOVO button when the computer is turned off and then select "Boot Menu".
- Select your USB/DVD from the boot menu.



Here is info about UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style): link






Note: The UEFI firmware settings determines what type of boot devices are available in the boot menu: UEFI, Legacy BIOS (aka CSM), or both types of boot devices.

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

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. Leave overclocking turned off. (If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install.) Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

DISKPART

SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE

Next click Install Now, then Custom install 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.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.

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 think it may have been deleted when I installed Windows 8.1 initially because i had to convert from MBR to GPT. Or so i read on one of the forums.

Is it possible to restore my UEFI partition so that I can use windows to enter the bios setup. I've had the boot on ultra fast and it took me a week to get into the bios without using the delete key. I had to use Gigabyte utilities which include drivers that crash windows. So i want to remove them again ASAP.

Any help appreciated.

A:UEFI option instead of Bios boot

Well to get back into UEFI mode you will have to reinstall in UEFI mode there is no other way, Sounds like some how your OS got converted to MBR so It may not boot either MBR or UEFI but you can't convert back to UEFI you have to Reinstall. If you have data on that disk you need to recover you can pull the drive and hook it up USB to another computer and recover your Data.

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.

Cheers

It ONCE booted into Windows, but then wouldn't let me through.... it locked me out? PLEASE GIVE ADVICE, I WANT TO DIE BECAUSE IT'S SO FRUSTRATING. NOTHING I FIND ON THE INTERNET IS WORKING. (Btw, I have Z170, not s87 or whatever. It's a different format?)
 

A:Stuck in UEFI Bios. Won't boot to Windows 10

Did you try to find somewhere "booting device settings"? If system was installed on drive you put out, you might have to set it as booting device again.

I built a computer back in 2009 with an Intel DP55KG motherboard running Windows 7. So, I am getting for a fresh Windows 10 install and I noticed that back in 2009 I never enabled the UEFI boot mode. Would it be recommended to enable it this time before the Win 10 install, or will it bring about some issues?

Here is the definition of the setting according to the motherboard manual:

UEFI boot
OPTIONS: ? Enable ? Disable
Enables or disables Unified Extended Firmware Interface (UEFI) Boot. UEFI Boot must be enabled in order to boot to a drive larger than 2 TB (terabytes). Enable: BIOS will attempt to boot via UEFI before using the legacy boot sequence. Disable: BIOS will use the legacy boot sequence.

Hi guys, I'm trying to properly dual-boot Windows 10 Edu 64bit and Kubuntu 16.10 64bit. The problem is that on startup it's impossible to start GRUB, Windows is loaded automatically. Is there a way to change UEFI boot order? I tried several methods but Windows always overrides my changes; I managed to load GRUB only once by renaming the Windows OS Loader path to the GRUB one, but after I booted to Windows once again, it overrode my settings creating a new Windows OS Loader entry. These are the methods I've already tried: Renaming the path as I said up here through bcdeditUsing EasyUEFI to change boot orderUsing efibootmgr in KubuntuUsing boot-repair in KubuntuUpdating GRUB in Kubuntu While on my desktop I have a BIOS setting that lets me change UEFI boot partition, I don't have anything similar on this laptop. Let me know, thanks.

Hello all,
I am trying update my system BIOS.
The System Board has an update for it.
Boot to Windows 10 UEFI does not enable the USB mouse and keyboard, and I do not have a PS2 combo to attempt, although I am not sure that will work either, depending on consensus.
Might this be Legacy BIOS/UEFI mode related?
Boot partition has prefix part. for UEFI (100MB) and is Healthy.
Boot disk is Basic GPT off a Samsung 830 120GB SSD.
SSD holds Windows only on it.
I have tried other ports onboard USB 3.0 as well as 2.0.
Any clarification would be most appreciated.

A:USB Mouse does not work | Boot to BIOS/UEFI

The USB mouse and keyboard should work fine - make sure it is plugged into the USB 2.0 port. A wired mouse and keyboard may be better but even the wireless versions should work.

Can you use an ASUS Bios update utility to update it so that you do not need to go into the BIOS but can do it from within Windows 10?

Heys guys, I'm hoping I can get some help with this. I have a Lenovo y410p. It has 2 drives, one with the OS (120GB SSD 40mm N.2 NGFF) and a data drive(1TB HDD)
My computer recently crashed when I was installing a piece of software, (Bentley MX Road, it's a road alignment package.) When I restarted my laptop I was greeted with a lovely message informing me that winload.efi was corrupt. That was fine so I did a bit of research to fix it involving getting a recover DVD and going to the command prompt to rebuild BCD. That didnt work for me as it didnt detect windows. I tried to see what was up with the SSD using DISKPART & CHKDSK. Neither of these showed the SSD. They only showed the HDD
So now to take a step back, In order to get the recovery DVD to boot I had to change the boot option in the BIOS from UEFI to legacy support. This showed me a list of bootable devices (HDD, SSD, DVD etc.) When UEFI is selected only one option is available which is the Windows boot manager. This is followed by the serial number of the HDD which does not have any OS on it.
I have tried using f12 which give me the windows boot manager option and nothing else. When I select this, it boots me into the error message.
So to get to the root of this, how can I change the boot order when the BIOS is set to UEFI so I can repair the winload.efi file on the SSD. Thanks for any help.

A:Changing boot order when BIOS is set to UEFI

You change it the same way as before. Usually you can do it withe the OEM software installed on Win8.

You may have to turn off Fast Boot if set.

I can't enter my BIOS/UEFI after activating "MSI Fast Boot" in the BIOS/UEFI.
I read somewhere about "GO2BIOS",but my installation disk didn't came with that software.

MB: H81M-E34 (MSI Global H81M-E34)

A:Can't enter BIOS/UEFI (MSI Fast Boot)

There is a utility called fast boot, is that on your disk?
If not you can get it at the MSI website. That will allow you to disable fast boot and enter the BIOS.

After upgrading to version 2.4.2 of the BIOS for Dell XPS 13 9360, I can no longer PXE Boot...the UEFI Network Stack no longer shows IPV4/IPV6 options in the boot menu, or the BIOS settings.
I compared the BIOS setting for setting with another unit that has version 1.3.7 and they are identical.
I'm using a USB-C Ethernet adapter (DELL p/n 96NP5) and a USB-C Docking Dongle (DELL p/n DA200), and neither of them work with this BIOS revision.
There doesn't appear to be a supported downgrade path from this BIOS version either (I've attempted 2.3.1, 2.2.1 and 2.1.1 and even though I have the BIOS downgrade option set in the BIOS, these versions halt stating that it is unsupported.  So I'm not sure what to do to resolve this issue. 
I called support, but the agent was asking me a bunch of Windows driver questions....even though this is prior to booting into Windows so I'm unsure why that is relevant.  She eventually put me on hold and the call disconnected after 10 minutes.  I've contacted my enterprise salesperson who can hopefully put me in contact with someone higher up, but if anyone here on the forums has any suggestions, please let me know.
Thanks!

Asus G73sw Laptop that I have used every day for the last 2 years.

So, I got the message: "Reboot and Select Proper Boot Device, press any key" so I tried another working HDD that has windows 7 on it; same message. I took apart the computer and checked the connections and cables. One time, during the constant restarts with other HDDs, I got the message "A Disk Read Error Occured." When I entered the BIOS menu, It recognized the HDD. Also, on the Easy Flash, I could see that HDD and its files.

Finally was able to load windows with UEFI mode. I am unaware what this is, but I assume it will work for now?? I have made no updates to windows 7, installed no drivers or programs recently, and am unsure why BIOS won't load any of my HDDs to windows, when BIOS clearly sees it.

Can anyone help me with this issue?

Thanks

OK, you cannot take a hd with windows already installed and put it in another system then expect it to boot. Not going to happen unless the two systems have very similar or identical hardware.
Finally was able to load windows with UEFI mode.Click to expand...

This allows windows boot mgr to take over the boot process. This is not the only difference; there are many. UEFI uses GPT table, can address larger hd, and a lot more. Here is an article that explains uefi in more depth;

I am interested in buying a Plextor PCIe SSD M6e(A) Black for a performance upgrade.
Plextor SSD Storage Solutions | Products | M6e(A) Black Edition

I emailed Plextor support with a system compatibility question & they replied within 20 minutes.

He stated: "Check your boards bios to see if it has CSM and that it is enabled
because you will need this feature enabled to boot from a PCIe drive."

I have a ECS A890GXM-A v2.0 mobo. details at:
ECS > A890GXM-A (V2.0)

and it does have a PCIe x4 slot (Gen2, PCI v2.0 compliant) but does not have a UEFI BIOS nor can I find any reference to Compatibility Support Module (CSM). Does this mean I cannot use a SSD with a PCIe connection or are there work-arounds, hotfix's, etc. to make this work? I have read that Windows 7 is a little finicky when it comes to SSD PCIe connections/drivers and such. Thanks!

So I made a usb stick as I normally do.

Laptop detects it fine and can boot of it, laptop is old style of bios.

I tried to disable fast boot, disable secure boot, but still its bypassed.

Ironically a older usb stick I have with a 32bit windows on boots fine.

I noticed in the asus bios, on the drag drop boot order page the usb stick has [uefi] written next to it and isnt an option to boot it without [uefi] is this related to the problem?

The dvd drive has 2 boot devices one with uefi and one without.

Note I dont want to make a specialised uefi boot media, it has to work on old and uefi bios's.

So I have a 100-15iby that's out of warranty, so I decided to try Linux on it (works great, unless you leave it doing a distro upgrade overnight and a power outage happens and the battery dies, requiring a reinstall) So I go to re-install and I try and boot from the USB, and it says "Boot from USB <Verbatim Store-N-Go> has failed".  This raised an eyebrow, and I thought it might be a bad thumb stick, so I try another, a Kingston drive. I load up the boot menu and the option for USB says "EFI USB <Verbatim Store-N-Go>", which is weird because any other time I've tried to boot from this Kingston drive it said the name of the Drive next to the USB option. Tried to boot using Legacy mode, but that only brought up the UEFI boot menu, it was at this time that I noticed that the UEFI Bios isn't saving settings.  So I take the laptop apart, pop the CMOS battery out, hold the power button for 15 sec to hard-reset, then power on/off for good measure, put the battery back in, closed the laptop up and powered it back on. And the Settings were still there! GRRRR... It still boots into Windows fine, so I know the laptop is working, so at this point I'm thinking the CMOS battery is dead (which if this was the case, I should have been able to clear the settings, but no dice), or there's something wrong with the Bios or Mobo. I can't revert the Bios because the setting for allowing a reversion is disabled and can't be enabled to al...
