Cannot access Bios, Please press DEL or F2 to enter UEFI BIOS settings

Q: Cannot access Bios, Please press DEL or F2 to enter UEFI BIOS settings

Hi Guys
I restored an image created with Macrium Reflect on my wife's computer (Custom build with Asus P8Z77-V LX mother board) and everything went fine until rebooting when i got to the "Please press DEL or F2 to enter UEFI BIOS settings" then everything stopped.
I have tried F2 DEL F8 F12 just about all the F combinations and nothing works, I have two SSD drives one with Win7 Pro and one with Win10 Pro (not connected at the same time) and neither of them will boot up.
I have tried changing the jumper pins from 1 and 2 to 2 and 3 for 10 sec to clear the RTC Ram in CMOS then returned then to 1 and 2 and tried rebooting...no change so i removed the battery and repeated the jumper pin swap then reinstalled the battery and still no change, cannot get passed press DEL or F2 to access the BIOS settings.
I even downloaded the latest BIOS and updater as shown and put them on a USB flash drive together and tried the Macrium Rescue disk, and still nothing happened and it will not open the BIOS maybe i got it all wrong ?
I was hoping someone here might know how to put it right, i am out of idea's and any help would be greatly appreciated.

Preferred Solution: Cannot access Bios, Please press DEL or F2 to enter UEFI BIOS settings

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.)


I have a Yoga 3 14 running Windows 10.  When I try to restart into EUFI Settings (following instructions http://zd.net/2fK7Zjw), machine boots up to a blank screen.  Computer is seemingly on (eg: cap lock button light and screen backlighting turn on and off), but nothing is visible on screen.  Powering off and on restarts computers successfully back to windows. Thanks for your help!

I have a Samsung 950 PRO NVMe M.2 SSD (512 GB) connected next to the original 512 GB SSD (Samsung MZVPV512HDGL-000H1). When I have the 950 PRO in the Studio I cannot enter BIOS settings. The Studio just stops (hangs) if I try.When I have the drive in the Studio and upgrade BIOS the Studio stops (hangs) during reboot. I have to open the Studio and remove the SSD to be able to perform these two tasks. Then I can insert it again. Otherwise the SSD is working nicely in Windows... This is the strangest thing that I have encountered for years! Anyone else have encountered this? Any workaround?

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.

40GB DDR3 Quad

GTX 1060

Upgraded Video Card from GTX 560 Ti to GTX 1060 Strix, machine boots but no video output or just black/blank screen.

Did a bit of online research and realize that two ways of fixing this
1. Change PCI setting to Legacy in BIOS/UEFI
2. Update to latest BIOS.

I decided to try and update BIOS to latest BETA (13w) using @bios from Windows. Everything went ok, reboots fine and still does now with Windows loading no problem, BUT i can't get to BIOS/UEFI???

All i get is the UEFI empty blue screen, no menus/options, just blank screen...

So i thought maybe i can reverse back to previous BIOS from windows but program wouldn't allow this. I tried sticking BIOS file in USB but the problem is i can't get to BIOS.

I Have tried running backup BIOS as board has two, but still same problem.

Good evening!
A week ago I reinstalled Windows 7 in EFI mode on my laptop, and now I've got this problem: whenever I turn on my computer after a shutdown, the BIOS says "System Resuming" instead of "Press F2 to enter settings". This makes impossible for me to access BIOS settings. Previously, my BIOS used to say "System Resuming" only after a hibernation. The weird fact is that - as far as I remember - this thing started happening only after a few days.
Can you help me?
Thanks in advance :-)

A:I can't access BIOS settings because BIOS assumes Windows is resuming

Try doing a shutdown command from a CMD window, or Start button / Run
The command is shutdown /s

See if entering the command manually makes a difference in how it starts up

This is my first post here, so hi to everyone.
I just got an ASUS X401a Notebook and I want to use a flash drive to boot from Linux.
I need to change the sequence in the BIOS so that the flash drive is first choice to boot from.
I have no problem accessing the BIOS utility, but it allows me to alter only some settings. Those in blue colored font I can change those in black font I cannot. What drive to boot from first is in black and not adjustable.
I used command line to work as admin and I also set up a password for admin in the BIOS to access the BIOS utility, but still no go; some things are allowed to be changed some aren't.

Any help is appreciated.

Satellite C850-F0055 laptop

I am trying to figure out how to access the boot menu at power on.
I have tried f2 & f12, f2+fn & f12+fn, tried holding the keys, tapping the keys
holding for 1 second etc, I have tried all the f keys as well, tried esc, backspace
ctr+ del nothing works.
what happens when I boot up, within 1 second 'Toshiba Innovation' screen appears
and then proceeds to load Windows 8.1.
I can access BIOS/UEFI via charms-pc settings and navigate to UEFI and get in that
way but that won't help if I need safe mode.
My settings are:- ODD/USB/HDD, boot speed set to 'normal', Secure boot disabled
I have a dual boot system with Windows/Linux.
If I put a boot disk in and power up, the boot option is totally ignored but with the disk still in
and Windows loaded and I access UEFI via the above route, enter UEFI and exit again
immediately the disk bursts into life and loads the disk as is supposed to happen at start.

I have not sure where to go now so any help will be appreciated

Cheers Rozzer

I am really confused on what settings are required in the UEFI Bios to run recovery USB/ disks or Linux live CDs.
It all used to be so simple. The manufacturer helpdesk seems unaware that it supplies UEFI systems - so I am working blind. Have tried boot CDs and USBs but all have booted straight into Windows to date.
Perhaps there is a basic guide but I have not found one yet.
I don't wish to change settings I have no understanding of.

I have a Medion /Lenovo desktop with an AMI UEFI Bios (12 July 2012) and Aptio Setup.

The following seem relevant are supplied as enabled in "Bios":

Intel Rapid Startup Technology
Quiet Boot
Boot Select Mode [UEFI]
UEFI Hard Disk BBS Priorities - Boot Option #1 - Windows Boot Manager
Secure Boot - Secure Boot Mode [Standard]

What do these all mean and what effect do they have on how Windows 8 runs and how boot drives run?

A:UEFI Bios Settings for Windows 8

To boot a DVD/CD/USB drive, the bootable software DVD/CD/USB disc need have full supports Windows 8, UEFI, GPT & Secure Boot & signed by Microsoft.

Boot the disc in UEFI mode from the One Time Boot Menu, check your manual for the F? key.

According to the Users Guide, F2 is the right key. I think you need to keep trying as you may be hitting it at the wrong time.

Hi Guys,
I've been trying to solve an issue I have with a laptop I just bought (warranty period over). This has been driving me nuts. I tried every solutions  I could find online to no avail. I saw that many people have a similar problem (but in most case they can't boot in the OS). I'm out of ideas here so if anyone knows anything about this issue, please enlighten me.
Here goes:
Laptop: Dell Latitude E6530 with nVidia card NVS5200M with Optimus + Intel HD 4000 graphics.
Service tag: 8HFKJX1. Latest BIOS A20 installed successfully. Fresh install of Window 7 SP1. BIOS set to legacy boot mode, Fastboot set to "thorough"
My problem is: I can no longer enter into BIOS settings. Weird thing is, the computer boots normally and everything else is working just fine. All the peripherals work as expected, both graphic cards perform normally, keyboard, everything, name it...
I was able to enter BIOS when I receive the laptop (F2 at boot). One of the first things I did upon receiving the machine was to upgrade the BIOS to A20 per Dell instructions (using a bootable USB key into DOS). After that I could still enter BIOS (F2 during boot). Next I performed a fresh install of Win 7 SP1. I could still enter BIOS at that point, then one day out of the blue, I could not enter BIOS (There is no BIOS password BTW). I have no clue what caused this or at which point exactly this occurred.
So here is the sequences that causes the problem:
1- I power up on the laptop

My PC will not boot nor will it access bios settings by pressing F2 during boot process.

About 6 weeks ago after an automatic Windows update my desktop PC became afflicted with the ?Critical Error ? Start menu and Cortana aren?t working etc ?

I resolved the matter by restoring my PC back to a state it was in few days earlier.

Yesterday the Critical Error ? start menu problem came back. When I tried the restore back to an earlier state the restore didn?t work and the PC just hung.

Now I cannot boot or access the bios settings. I tried booting directly from a Windows Disc but that will not work either. It will not boot in safe mode either.

Whereas I can understand that the unsuccessful restore may have corrupted the operating system I cannot understand how the BIOS will not work and why I cannot get into BIOS settings

I have tried booting from a Windows disc but it will not do so - seems to me that the BIOS is bad

I would really appreciate if anyone could give me a few pointers on what to try out

Many thanks

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...

A:Satellite Pro A300-1LG - cannot enter BIOS settings

To be honest I?ve never heard about such problem. It is pretty strange due to fact that you can enter BIOS from time to time.
I don?t think there is anything you can do about that, except to set BIOS to default settings. In my opinion BIOS update is not the solution. BIOS is the first and lowest hardware check level and notebook users don?t have much possibilities to do anything about that.

I?m afraid you need professional help with this.

hello everybody here at B.C

As this topic mentions this is supposed to be a BIOS guide, not exactly tho....
I will write about what i have encountered and worked with when it comes to this motherboard in hope to expand this knowledge and hopefully finding a solution with a broader network.

As mentioned this is the ABIT AN8 Fatal1ty S939 Motherboard without the SLI = double PCI EXPRESS installed
Basically my old motherboard stopped functioning so i had to replace it with the Abit Fatal1ty, at first i was very pleased becouse i read alot of positive stuff about it, altho i dont really like too much advertising this motherboard looked promising.
A part of the horror that struck me was that i needed to install WinXp from start, there were reports of users who could simply do a repair of winxp so they wont loose any valuable data, but in my case i didnt have that option, my windows could not be saved. Since i had 3 HDD's i plugged in another one after backing it up from another pc, becouse i simply mistook it for the hdd that had winxo on it, anyway i thought to myself i could backup my winxp containing drive at a later state when i get winxp installed on the drive i just cleaned. I then instaled all the hardware where it belongs and booted up and put in the WinXp SP2 cd and ran thru the first part of the setup ( where the files get copied over to your hdd before the restart )
All went well and the pc gave me as usual a 15 second timline to restart or it would do it by its... Read more

A:Bios's ( Disk Boot Error Please Insert System Disk And Press Enter )

Simply put, the disk that you think that you are booting from, and the disk that you are booting from, are not the same. I did the same thing myself not too long ago. Pull out the other disks and install XP. Once it is working, then install the other hard drives. If you are sure that you are booting from the same drive on which XP is installed, then the disk is thrashed.
You said you took out a disk from another system and it booted fine. How about trying this? Take the disk out of your system that you think is the one with XP on it, and see if if it will boot the other machine?
This is no huge mystery. It can only be one of very few things.

I apologize for the inconvenience caused to you. You can follow the steps below:
Drain the residual power of your computer and recaliberate the battery by following the steps below:

Power off your computer. 
Remove all the external peripherals  (printers, scanners or any other USB device) connected to your computer.
Please remove the AC adapter and battery of your computer. 
Press and hold the power button of your computer for 10-15 seconds to drain the residual power. 
Release the power button
Keep the battery out for atleast 2 - 3 hours.
Then insert the battery and charge it overnight with the system powered off.
Insert the battery in and connect the AC adaptor.
Then power on the computer and see if it works.

If the issue still persists, you can update the BIOS of the computer.
Note: Make sure the ac adapter is connected and the battery is charged 10% or above to update the BIOS. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.

Not sure if this is a Boot or Operating System issue so let me know if I need to move this to the other board. I'm trying to enable virtualization on my computer, which can only be done from BIOS (or apparently in the case of Windows 10 UEFi). I've followed various tutorials online to access UEFI (Shift + Restart > Troubleshoot), but when I get to the troubleshoot menu where there should be access to UEFI-Firmware, there's just a link to Startup Options/Settings (I can't remember the name of it exactly as obviously I don't have it in front of me right now). From what I've read the access to UEFI can vary depending on manufacturer, so I was wondering if HP might have moved access to UEFI somewhere else? Any help ASAP would be much appreciated as I need access to this to study!

Hi, You should be able to access this as follows. Shutdown the notebook. Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  The option to enable virtualization should be found under the Advanced tab.....Device Settings.....Device Configuration. Regards, DP-K

I purchased this destop in February, but am having poor font rendering problems in Windows 10. I thought perhaps it was caused by some software I installed, so I opted for a complete reset, (eliminating all my files). It went ok, except the American Megatrends screen comes up during each boot/reboot, requiring me to press ESC. It also asks if I want to completely clear the TPM by pressing F12. But pressing this does nothing, only ESC will get me out of that screen. When following the boot interrupt sequence, I can get to the boot screen but not into the bios.  I tried clearing the TPM through TPM manager, but following those instructions just restarts the machine but still does not let me access the bios (it cycles back to the Windows welcome screen then to the TPM manger). Today I reinstalled Windows 10 yet again, this time from my backup USB stick. The American Megatrends sign still comes up, so it looks like something got reset in the BIOS. If I could get in I would turn off the TPM....Any ideas on how to get rid of this annoyance? --Btw, the poor font rendering is still there but that's "research" for another day.

I solved this myself. After realizing that there is a very small window of opportunity to press the various ESC/F1 etc. buttons I finally managed to get into the BIOS/UEFI, found the TPM under the Security tab.

Hello my friends ! A time ago i bouhgt two Lenovo ideapad 100 14 IBY (FreeDos Version) and install Windows 10 on it with UEFI and GPT Partition Table. All works fine until i want to play around with Linux and install UBUNTU Mate in UEFI on one of them. The install was easy but the Performance on Ubuntu with Bay Trail and the don't working Bluetooth was a reason to switch back to Windows 10. After that the Problem beginns. The Bios don't let me save changes anymore (only time and date !). There was no UEFI ESP and GPT Support since i install UBUNTU and the Bios Menu looks like that:Bios Entries on a blank DiskBootingThe Disk is Blank there is no ubuntu on there (Don't know waht the EFI Entries are no Hardware is connected). And when I boot also go to Network Boot there.(No Matter a USB Stick is connected). So what i did: # I Dismantle it and disconnect Battery and Cell and wait half an hour. # Nothing changes !# I change the HDD. # Nothing changes !# Reflash the BIOS by edit the plattform.ini - CheckByBios=1 - Error Cannot mount EFI Partition. # Nothing changes !# Install Windows 10 - Make mbr2gpt.exe and bcdedit and bootrec. # Nothing changes ! I can install and run Windows 10 in MBR and BIOS Mode on it. But no USB Stick was displayed in Boot Menu. So now Iam on my Limit and the Question is there a way to put UEFI and GPT back on it or does the BIOS locked in this State. For me UEFI is MALEWARE so why can a simple UBUNTU damaged my BIOS and ...

Hi There,

I just built a desktop with a sabertooth x79 motherboard, and am running Windows 8.1 pro 64-bit. When I click the UEFI BIOS Firmware live tile via the change PC settings>update and recovery>recovery>etc. my computer reboots normally to Windows and will not open BIOS. I have tried accessing it using the delete and f2 keys, but this does nothing either.

Any ideas? I am up to date in terms of my BIOS, and am definitely running UEFI and not legacy.

Thank you so much.

A:can't access UEFI BIOS and BOOT menu on my lenovo z580

I own a Lenovo G700, and I have heard that Shift + F2 will get you into the BIOS. It might work if all else fails. You can also call Lenovo support or search around a bit more. But in my case I have to use the hardware OneKey Recovery button to access it.

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?

A:UEFI BIOS Access, Changing Boot Drive Order To SSD

Hi, No, you can't do that. You have to swap SSD and HDD. Put old HDD to the caddy. Regards.

I had a strange set of circumstances today. I was trying to update my memory from 2 to 4g. My system would not boot with the new memory and the bios gave 3 beeps. After removing the new memory, the system would boot to XP but I had no video. I powered down and powered back up. I now had video but the system would hang. In Safe Mode, it would hang after the following entry system32/config/system. Note I never observed any windows error messages, just the hang.

I used the Recovery Console from an XP CD and did a chkdsk /r and chdsk /f
I also ran fixboot

None of these solved the problem.

I then ran fixmbr
Recovery Console displayed some kind of caution message that I had a "invalid" or something MBR and that it might prevent me from access partitions or something.

Well, I ran fixmbr anyway since i was out if ideas.

Now when I try to boot, it is freezing during the post process. When I hit F2 to enter the BIOS setup, it says "entering setup" but it never does. It seems to be hanging right after the drive detect process.
Note I have one standard IDE drive © and 2 SATA drives. Windows XP is installed on one of the SATA drives.

Any ideas? Let me know if you need any more info.

A:BIOS Hang, unable to enter BIOS Setup after running FIXMBR

This sounds more like a BIOS = hardware issue. Since you have been inside the case it is possible something got nudged loose. Re-seat your memory and video card if it is an add-on.

My laptop has no problem before. Recently I try to install Windows XP. First attempt fail, so I change SATA at BIOS from AHCI to Compatible, success. However the partition that I want to install*Windows XP to is not available.*

So just to test I choose my Windows 7 partition. Since it want to format the partition, I cancel the installation. After restarting windows, it stuck at bios. I restart again and change SAT to AHCI. Restart, still stuck at bios. This time I cannot enter BIOS, recovery or change boot media. Assuming the boot sector has corrupt, will reseating the cmos battery will fix this *problem. Please help. Thanks in advance.*

A:Windows 7 Stuck At BIOS Cannot Enter BIOS or Change Boot Media

Somehow with guidance from Lenovo Community, I solved the problem.

For future reference:
1. Take out HDD, battery, plug off ac power.
2. Restart, change SATA Controller in BIOS to compatible, restart.
3. Check whether the SATA Controller is Compatible or AHCI. If Compatible, force shutdown laptop.
4. Put back HDD, boot with Windows 7 Recovery CD or Installation Disc.
5. Choose Autostartup Repair.
6. Restart.

At the beginning, it wasn't much of an issue. I were able to upgrade from Windows 7 to Windows 10 like usual and there weren't any problems, except that I couldn't boot from USB, which is an option locked by the BIOS.I attempted to get into the BIOS using all types of passwords, but all were wrong and I were able to get into the BIOS after 3 wrong password attempts but I weren't able to change most of the settings (including the boot from USB option).I tried to find a way to remove the password using software, and according to many recommendations, I installed the CMOSpwd program and tried to remove the password.The laptop rebooted, and there's were my issue is now.After the start-up screen, the next screen shows:  "Error 0271 - check data and time settings", then it goes to the screen where I should enter the password, but this time I can't enter to the read-only BIOS nor the Windows 10 so I got no choice but to get the password from somewhere, which I am unable to do since this is one old laptop.I am not in much of a hurry and any help is appreciated.Thanks.

A:Unable to enter T400 BIOS or Windows due to Error 0271 - check data and time settings

Welcome to the forum.
The normal action when you get "Error 0271 - check data and time settings" is to go into BIOS and set the date/time. You will need a valid password to get into BIOS to change these settings.
This forum has a policy that discussions about circumventing passwords is prohibited. If you want to pursue this option you will need to do so elsewhere.

I have had this H50-55 for sometime, several years and suddenly it ask for a bios password when I try to enter the bios to change the boot order.  I have no clue what it is. I hate passwords and NEVER use one unless forced...What can I do?

A:Lenovo H 50-55 Bios password suddenly appears when trying to enter bios. I don't know it.

my guess is that your cmos battery died and it wants you to set day/time.  There is no backdoor password.  The choices are remember the PW or replace the motherboard.
