Dell XPS L702X :: UEFI Mode Enabled But Can't Access Firmware Setup And Boot Menu
Oct 28, 2012
Yesterday I flashed the firmware of my XPS L702X to version A19, which enabled UEFI boot mode. I decided to go ahead and try to install Windows 7 in UEFI mode on a GPT disk. Installation succeeded, booting failed however. Then I read a message on the web from someone who succesfully installed Windows 8 on the same machine in UEFI boot mode on a GPT disk. So I decided to try Windows 8 instead. Installation failed. Using the recovery menu from the Windows 8 installation media, I wanted to try and see how far installation had come and more or less accidentally selected in some "Advanced options" menu to reboot to my USB flash drive (where the Windows 8 files were on). Rebooted fine. Then I shutdown, using the regular option.
When I turned on my machine again, I found out that pressing either F2 or F12, for the firmware setup and the boot menu, respectively, didn't work anymore. The firmware recognised my input, as the text in the lower right of the Dell splash screen became lighter, but instead of entering setup or the boot menu went straight ahead to boot my existing and working Windows 7 installation on my first (MBR) hard drive instead.
So, in short, I am locked out of setup and the boot menu. I have already tried reflashing the firmware, but without any luck. What to do now?

I have a XPS 17(L702X) with Window 7 Ultimate 64 bit and am in the middle of a Dell support issue regarding the Nvidia graphics card.
Dell support have requsted I run diagnostics from the "one time boot menu" (I have run this before on other laptops but my problem here is.
Dell supports says tells me "Immediately press the F12 key once every second until ?Preparing one-time boot menu?, Shows in the upper right corner of the screen."
However all I get is "Boot Menu" (With options underneath) in the centre of the screen. Is this the same thing?

I received my Dell Inspiron 15R - 5520 laptop and am attempting to set it up to perform a UEFI boot to a Windows 7 (64 bit) installation. I am using bios version A11 which is the latest available.
If I use legacy, I am able to boot fine to the Installation DVD and install/use the system. If I use UEFI (non-secure boot), it will freeze during the boot process for a long period of time. I do not ever get to the GUI to attempt installation. I have tried clearing the disk partitions using diskpart -> clean to ensure it is not due to having GPT vs MBR and have also tried changing the SATA adapter to ATA vs AHCI.
Alternately, I am able to boot to, and install Windows 8 RTM in UEFI mode.
Before I get a lot of responses of "Don't use UEFI", the reason I purchased this laptop was for the purpose of dual booting between windows 8 and windows 7 for development purposes, and require the use of secureboot to properly test the software I am developing. If this laptop is not able to run Windows 7 in UEFI mode, I will need to return it and select an alternate vendor.

I just got an acer aspire timeline 5810tz, which came with vista, so i was in the process of reformatting it to have XP, which i've done several times on my previous laptops. When i changed the bios to IDE, which is what i read was the correct setting (perhaps this is where my problem is?), i found that i could no longer boot the computer or access setup, bios or the boot menu. When i attempt to do any of these things, the computer just sits on the logo screen.
i'm getting fairly desperate at this point, having tried a large variety of solutions, key combos, removing the battery, etc.

Is there any way I can enable UEFI booting? I've found out Windows 7 supports it (with GPT disks as well) and Windows 8 is going to use it. This is also very useful for fast booting and Linux works very well with this (I know you don't support Linux). The main reason is so that I can have more than 4 partitions which is only otherwise possible using Extended partitions which don't play nicely with installing Windows on them. If there is a firmware I can test which may not be fully compatible with BIOS booting, I'm willing to use it as I don't need this feature at all. I also noticed there was a disabled option in the firmware provided which allows you to press F11 to boot into an UEFI shell, is there any way to enable this too?
My charger end keeps on falling out of my laptop and is very loose. How would I go about getting this fixed?
The A12 BIOS seems to keep my fan constantly on (only just on though). Was there something that was changed in the firmware to cause this?
Some people have reported having the BIOS versions A13 and A14 installed on their new L702X machines. What are the changes in these firmwares and are they for specific configurations?

Many of us have brought Dell XPS 15s (L501X) an year ago - they are working great.
However all recent laptops now are coming with UEFI as default, with a legacy fallback option.
I believe current bios (A08) is actually a locked version of Phoenix Tiano Core UEFI.
Does dell have any update or is at least planning to launch one soon?
We need it for full functionality of Windows 8 and get it boot from gpt..., otherwise l501x is a powerful enough machine with i7 & a hot nvidia gpu.

I have recently been completely unable to access the set-up area of my bios on my Dell XPS 17 L702x laptop. On booting, i keep pressing the F2 key which seems to be registered by the BIOS as the text that says 'Set-Up' lights up. However, instead of entering the setup, the BIOS simply continues booting my operating system. Even if I remove all of the hard drive's, I cannot enter the set up and the BIOS boots to the PXE Setup.
I have tried reflashing the BIOS but nothing changes, the set-up is still inaccessible. I can't even change the boot order using the F12 key.
I really need access to my BIOS and I am all out of options.

I have a HP 2000-2b19wm laptop. I bought this system. It came with Windows 8. After I got it I completely got rid of Windows 8 and IMHO upgraded to Windows 7 Ultimate. I deleted all partitions and let 7 configure the hard drive the way it wanted, got the drivers and so on and so forth. (not worried about warrenty, I can handel most hardware repairs and software fixes).
I looked to see if there was a new BIOS available and there was, However I also noticed that there are two things called HP UEFI Support Environment and HP Unified Extensible Firmware Interface (UEFI) Support Environment. I know they have to do with Diagnostics and recovering from a bad BIOS flash.Do I install HP UEFI Support Environment or HP Unified Extensible Firmware Interface (UEFI) Support Environment?

Acer Aspire V3-772G - BIOS setup utility menu items have disappeared
I have setup this brand new laptop, pre-installed with Windows 8.1, for my sister-in-law who bought it. The installation went well BUT the 16GB USB device which I purchased as advised by the Acer literature to store the recovery partition was not big enough, the physical capacity being 14.4GB. The Acer book says use a 16GB device or larger so I did. I naively thought that a USB drive which was labelled 16GB would be appropriate. Not so. I have had to buy a larger one but am still awaiting delivery.
I therefore decided to image the whole HDD to save the work I had done but found that the Acronis Backup and Recovery DVD would not boot. I went into the setup utility and adjusted the Boot settings to legacy and changed device priority. Acronis would not run so I did not continue. I went back into the setup utility, used F9 to restore the default and found to my astonishment that the DUAL boot option had now disappeared and the Windows Boot option had also vanished.
This means that this £800 laptop is now unusable. The setup utility self-reconfigured without warning. Nowhere is there any advice or warning not to use the setup utility in case it erases features which cannot be recovered by using F9 to recover the default configuration. If this is not a serious design fault, I don't know what is.
I am deeply worried because the idea of a BIOS setup utility behaving this way seems so improbable. How is it that the setup utility has been designed to self-harm like this?

I have an ao725-0687 netbook with windows 8.1 (from the factory). I wish to access UEFI (Bios). The method at [URL] {Accessing the UEFI (BIOS) setup on a Windows 8 / 8.1 system} does not work on my machine. My machine does NOT show the "UEFI Firmware Settings" button on the relevant page (but it DOES show the other 5 buttons shown in the video to be on that page). How can I access UEFI on this machine?

I recently bought a new E535 laptop working like a charm up to now. Bios access was possible by pressing Enter directly after switching machine one, than came some sort of POST analysis which could be skipped by pressing any key and than came some sort of table where I could access Bios by pressing some key (cannot remember which it was exactly). Alternatively I could enter Bios when in boot menu by pressing tab which switched to another tab where Bios could be entered (also some sort of diagnosis programs could be started). As mentioned in the subject it is impossible for me to do this now, after I did the following:
- exchanged built in HDD with an new SSD (Bios access yet possible)
- changed in Bios Setup boot mode from both (legacy + UEFI) to Uefi only (this might be the problematic point but I'm not sure)
- Installed Windows 7 in Uefi mode on ssd
No when I press enter on startup it brings me to Windows boot manager menu (you know where you can say start Windows normally or in safe mode and so). Boot menu also changed with a new "start windows" entry (well, this seems to be correct), but when switching to the other tab it is empty now, no entry for Bios setup or diagnosis tests anymore.
This is really bad. I have googled around and tried the following up to now without success:
- Pressing F1 instead of enter
- Shutdown laptop, and start with F1 pressed down
- starting without HDD
- starting unmodified HDD which was originally installed in laptop (which cannot be booted anymore, probably because it was installed in legacy mode)
I have also thought about flashing the bios, but the newest version available on lenovo support seems to be 1.04, but pre installed on my laptop is 1.10, so my version is a lot newer. Should I try to flash it nevertheless ?

After the upgrade to the current UEFI firmware, when I try to access to settings the BIOS ask me for a password. I'm absolutely sure I have not set any password (I hate BIOS passwords). Now I need to start from a USB pendrive and I can't change the startup sequence.
I've read the post about how Acer can support on lost or forgotten passwords("there are very few if no options available from the end user side"), but in this case I've not created any password, as I said

I've recently reset my laptop to factory default using the Windows 8 Reset option, and now when I want to access the UEFI settings I get a onekey recovery prompt instead. Is there any way to bypass it because I just transfered my files back and I don't want to reset everything again.

Everyone: Absolutely cannot boot from CD-DVD even if I turn OFF Secure Boot and UEFI and my machine lists my CD-DVD as a boot option. When I then try to boot from the CD-DVD, I get an error message. (Optiplex 7010 Mini-Tower with Win 8 Pro 64-bit, an Intel i5 3470 processor, 8 GB RAM and 500 GB hard drive. It has BIOS version A16 right now.)

For the last 2 days I have been trying to install Windows 7 x64 in UEFI mode on my laptop but it seems entirely impossible. Whatever I do, the boot menu (F12) just won't show any UEFI devices AT ALL, just the normal DVD and/or USB options. Obviously when I try to boot from either normal DVD or USB, Windows 7 setup freezes at the "Starting Windows" screen, I'm pretty sure that's because it is not running the EFI bootloader of the setup.
For the record, I can't just install Windows 7 in Legacy/BIOS mode because it is then impossible to install the Synaptics Touchpad driver under Windows because the Touchpad device is not discovered for whatever reason.

I have been struggling with installing w8 on my Ideapad z510 laptop in UEFI mode, but neither I could succeed it nor I could I find something that might work. I will clearly explain the case.
Point 1:
As I understood, to succeed w8 install in UEFI format, one needs to choose "UEFI First" mode from Boot Menu in BIOS. Then, the source of the boot needs to be specified to identify the rigid path to the documents to load so that new OS could be installed correctly.
Problem1:
It is possible to chose UEFI First from boot mode, but it's not possible to choose the USB path for UEFI booting in this case, which doesn't allow you to succeed a UEFI boot to your computer. You can't reach the DVD or USB, where the installation files are, and start installation process.
Point2:
Considering the first case, you need to choose Legacy Support mode to boot your computer and reach USB disk or DVD to install new OS on the computer.
Problem2:
To succeed UEFI mode booting to the computer, you need to see 4 different partitions on your disk at point of disk selection, where you choose the disk you'll install your OS. However, when you select the Legacy Support mode from BIOS, the disk partition is limited to 2 in my case, which are:
Primary diskSystem reserved (350 MB)Hence, when I continue with the installation, the OS is installed on Legacy mode. After installation, when I go to BIOS to choose UEFI mode for boot mode, the laptop checks some connections from network and says
EFI network 0 for IPv4 failedEFI network 0 for IPv6 failed respectively.
PS: Please don't tell that "you can't install, because your computer doesn't support", because I received the computer from technical service and a version of W8 was installed on it in UEFI mode. However I deleted it to install W8 pro.

I've got a new Dell XPS 15 four days ago. I've been having a lot of issues with its internal mSSD drive. The model I ordered has a regular 1TB hard disk and a 128 SSD. I was quite surprised to discover that the Intel Rapid Storage Technology (that allow faster data access by using the SSD as cache) is not enabled by default. I tried to enable it but no success. An "unknown error" message box showed up when I attempted to do so. That was really strange, considering that the only thing that I've done so far in my computer was installing MS Office and Google Chrome.I contacted the tech support three days ago and I was told to reset my computer to factory default and try again. After a long wait for system restoration I enabled the acceleration mode in the Intel Rapid Storage software.
Everything proceeded according to expected, but when I rebooted my computer it failed to detect any bootable device. I can't even access the system restoration by pressing F8 during initialization now. especially when we consider that this shouldn't be happening in a premium $1,999 model. Also, shouldn't this KEY feature (caching with SSD) be enabled out of the box?

I am having a major issue with my Dell XPS L702x laptop at the moment, in that it cannot boot up at all, rendering it completely unusable.
When this first happened, the laptop used to progress through the dell screen, the 'starting windows' screen, and then just hang at a blank screen, or with a blank screen with the windows 7 background and a mouse cursor. This happened in both normal startup and attempting safe mode.
I have tried starting in best last known configuration, resetting the bios to default settings. I eventually got startup repair to work, but it didn't do anything, nor did system restore.
I run diagnostics, and receive this error right at the beginning of the test:
ERROR CODE 0146.
Msg: Error Code 2000-0146
Msg: Hard Drive 0 - self test log contains previous error(s).
I continue the diagnostics and everything else passes okay.
However, now when I try to boot my PC up in normal or in safe mode, I get past the dell and windows startup screen and instead of the hang I simply get a blue screen error:
BAD_SYSTEM_CONFIG_INFO.
STOP: 0x00000074
I have also had the blue screen errors c000021a, and 0xc0000221. But primarily am now getting the bad_system_config_info every time.

I have a dell xps17 (l702x) laptop recently had a problem with it , that is it wouldn't start up and when i turn it on after 2 seconds it would just crash , so i changed the motherboard , processor and and it fixed the problem to some extent .. now my problem is i that when i turn on it loads to a certain extent then when it reaches the windows start-up logo it would just crash and restart again . so i tried the diagnostic test available by pressing F12 it dint show any problem .. looks like my windows got corrupted due to the sudden crash earlier
I tried to boot from the windows repair disc but it wouldn't boot ( i did change the boot up to cd / dvd) then i tried to boot up from the windows 7 disc , it would say "press any key to boot from cd or ddvd " after doing so it would load the files and and crash again at windows start up . i even tried the safe mode option . it wouldn't load it completely and get stuck , i tried to restore to the last good backup it would still get stuck at windows startup .

I own a Dell Latitude E5510. I *love* this laptop.
However, today I started having a problem with it. The laptop turned off suddenly. When I went to turn it back on, it began to load as usual with the following things on the screen:
1. the circular logo in the center of the screen.
2. the "press f12 for boot menu" thing in the top right corner.
3. the blue loading bar beneath the circular logo in the center.
What happens is the blue bar fills up, but then the screen goes black. It doesn't just instantly go black though. It starts from the top of the screen and moves to the bottom. It does the same thing when I press f12 to get into the boot menu.

I'm having getting my USB stick recognized as a bootable device (installing windows 7 onto a system that came with windows 8.1 pre-installed, no optical drive)
System: Acer E 15 (E5-571), BIOS V1.15 (UEFI)
What I've tried:-Disabled Secure Boot
-Created bootable USB stick with Windows 7 iso, via 'Microsoft USB/DVD Download Tool' (on alternate Windows 7 system)
-Created bootable USB stick with Windows 7 iso, via 'Rufus' (on alternate Windows 7 system)
-Windows 8.1 Advanced Restart -> Boot from UEFI USB Device (No UEFI device recognized)
What worked:-Enabling 'Legacy Boot Mode': USB stick was recognized upon boot and loaded Windows Installation. HOWEVER, Windows 7 won't instal to a GPT formatted drive under Legacy Boot Mode. I've read booting in UEFI mode is the only way to get Windows 7 to install onto GPT.
What I don't want to do:-Format the drive, change drive mode to MBR to instal Windows 7. Why? Because then I'd loose the factory installation of Windows 8.1

I got this laptop a few days ago, I currently have 7 and XP installed on it and kind of have vista...(read further down).
My 7 seemed to break today after playing around with a program called powerstrip trying to get my external monitor to show the right resolution (I've realised now the cable vga was broke, but meh) but this is not the full problem, after windows 7 failed to boot I tried to boot xp after turning it off during the windows 7 splash screen and now im stuck with a dash when I turn the laptop on (I dont know if its actully related to something I've done or not).
If I turn the laptop on a flashing dash comes on in the top right, it then stops flashing and turns into a none flashing dash further up the screen and just locks here and I cant do anything at all other than trying to restart it. When I had this problem previously (at least I think this problem) on my desktop it usualy turned out to be something usb related but I have everything unplugged (all though the bluetooth adapter light is on when it is doing this) so I realy dont know what to do...............
