[Boot Manager][SOLVED] Fixing UEFI Boot Issues: Black Screen After BIOS POST. Booting Only Possible From BIOS F12 Boot Menu

Q: [Boot Manager][SOLVED] Fixing UEFI Boot Issues: Black Screen After BIOS POST. Booting Only Possible From BIOS F12 Boot Menu

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...

Preferred Solution: [Boot Manager][SOLVED] Fixing UEFI Boot Issues: Black Screen After BIOS POST. Booting Only Possible From BIOS F12 Boot Menu

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.)


Computer won't boot after bios upgrade.Quick history- computer was working but was dropped, damaging hdd- verified hdd damage by removing it and connecting it to another computer- verified computer hardware still good by booting and using it from ubuntu live cd- purchased SSD- changed Bios HDD support to Legacy mode so I could install w7- installed w7 64 bit professional- install went great, computer booted in windows, no lan or wifi yet : missing drivers- downloaded drivers and bios update from HP site for my exact machine to USB stick using different machine- installed audio driver- installed bios update, did not tamper with machine at all during BIOS update followed instructions exactly- after bios update  s/w said bios flash was 100% complete computer just hung for 15 min's- repowered machine: only get black screen- holding down F10 while powering up gets white "F10...BIOS Setup Options" text in lower left corner of screen, nothing else happens,I tried holding the windows and B key before powering then for a minute after powering several times, nothing happened. http://support.hp.com/us-en/document/c02693833I repeated that procedure half a dozen times with and without a USB with the BIOS update software on it in a USB slot, no difference.  Does my model support this key combination to load deffault BIOS settings? Do I have any other options to unbrick my machine? Any advice is appreciated.Mike

Belarc reports UEFI: American Megatrends Inc. P11-B2
Operating System: Windows 10 Home (x64) Version 1511 (build 10586.494)
Installed: 4/27/2016 5:58:22 AM Servicing Branch: Current Branch (CB)
Boot Mode: UEFI with successful Secure Boot.

This is my brother?s computer: originally it was Win8, upgraded to Win8.1 and then in Apr to Win10.
--- The computer runs OK and I?ve shown him how to use MRF to create system image backups.
--- Today Aug 8 we tried to test recovering yesterday?s Aug 7 system image backup.
--- It didn?t go well at all.
--- The MR recovery DVD-RW didn?t boot up in order to test it.

I thought of disabling Secure Boot to see if that was blocking the MR bootable Rescue DVD-RW.

However we weren?t able to boot into either the UEFI BIOS or Boot Menu.
--- According to our notes DEL is used to boot into the UEFI BIOS and F12 is for the Boot Menu.
--- However when booting up: in less than a split second something scrolls up but the computer immediately boots into Windows to log in.
--- That?s much too fast to get into the UEFI BIOS or Boot Menu.
--- Please help us figure out what to do.

Following that I?ll have to learn how to ensure proper system image backups and recovery using MRF.
--- I don?t recall any issues when I had Win7 but re-training myself makes sense to me because it?s obvious I don?t understand it well.
--- For now I?m going to completely uninstall MRF from his computer and hope to start over with a clean slate.

A:Cannot boot into UEFI BIOS or Boot Menu

Try F2 or F8 while Powering ON.. (which you might already Have). If no go update BIOS(which you might already have).

Assuming you have Windows 10 or Windows 8.1 on computer.. Do a Shift + Restart >> Troubleshoot >> Advanced Options >> Change UEFI firmware settings...Restart.
U should be be able to boot in BIOS.

Sorry first time poster. I wasn't too sure whether to post to the Windows forums or hardware forums. From what I can see, this seems like a hardware issue of some sort.

The problem I have is that during bootup my PC goes through all the normal things. It detects my CPU, detects RAM etc. gives me nice BIOS Post messages that appear normal and then goes to a black screen. It will then sit there for 50 seconds (i've timed this twice) and then proceed to go to the windows XP startup screen (which takes about another 10-20 seconds to load up windows).

I've attempted to log the bootups by using the Windows Boot logger (by pressing F8 before windows boots). The ntbtlog.txt file isn't very descriptive, and only lists that a whole lot of drivers have been loaded, and some that haven't (it doesn't list any errors).

I've also tried using BootVis to analyse the bootup. I found this a little hard to decode the information it gave me, but there doesn't seem to be anything untoward happening.
The last boot logger I tried was bootLog XP (by greatis software). According to bootlog XP, windows is only taking 19 seconds to load up.

Can anyone suggest any other ways to analyse the boot sequence and discover where my computer is stalling?

(specs are below.)

Thanks in advance,


CPU: AMD Sempron 3000+ Socket 754 (unsure whether it is Paris or Palermo core)
MBoard: Foxconn NF4K8AB-RS

So i was playing Doom 3 and the game crashed so badly that i had to restart my computer (im running Vista 64bit by the way) and upon restarting it, it gets to the BIOS screen but after that it just goes black and nothing happens, i have tried the F8 thing but all that brings me to is this boot menu, but not advanced boot options, i have also tried pressing F8 or F5 after i selected hard disk from that boot menu, still nothing happens. So i cant access "restore to last good system configuration" because F8 doesnt take me to the right menu to do so. Also i dont have a vista install disk so am i SOL and have to just get another disk or upgrade to windows 7? or is there some other way to do this? Any help is appreciated!

hi sivasandeep99,
Welcome to Lenovo Community Forums!
If you have tried FN+F2 when boot?
Or holding down Shift and clicking restart?
If those steps did not work either,  You might need to contact Lenovo Technical Support and have the system shipped to Repair Facility for BIOS Reflash.
Found this article but it is for the same model that has same issue like yours.

A:Windows 7 and UEFI BIOS Boot Manager error 0xc000000e

What are the exact UEFI, CSM and Legacy BIOS settings in BIOS setup? Did you do a UEFI install, booting from a UEFI device to install, or did you install to Legacy MBR disk?

Unplug all peripherals and try again.

If you can get into Safe Mode, establish a Clean Boot from Troubleshooting steps in picture below. Then test your hard drive, RAM and work through the other steps to go over your install and hardware.

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've tried several things (turning off Secure boot, changing from UEFI to legacy bios--it won't boot at all that way) , but I can't get that second disk t... Read more

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.

I used to have a W7 system in IDE, MBR and since I had to reinstall everything from sratch, I decided to set my drives to AHCI, UEFI/GPT. After install, I checked the BIOS settings and saw that in my Boot Options I had the "Windows Boot Manager" set as #1, my SSD set as #2 and DVD drive as #3.
When I change the boot priority and set my SSD as #1, my computer won't boot and asks for a bootable device although the system is install on my SSD. I don't have a multiboot system, there's only W7 present so why do I have a "Windows Boot Manager" in my BIOS? I thought it was only for multi boot systems so I don't get why it's showing up here.
When I go to msconfig, startup, there's only one system displayed (W7).
Since I'm new to AHCI/GPT, I don't know what's normal and what's not. If it's not normal, how come I got this Windows Boot Manager in my BIOS? Maybe the old MBR wasn't erased even though I ran a secure Erase on my SSD?

Unless your controller supports hot swapping, I would NOT do that again.
Have you replaced the sata cable and or tried another sata pw connector?

FWIW just because a disk passes the drive maker's diagnostic, does not mean it is OK. I had a system a few weeks ago that passed ALL tests twice and I zero filled the drive; still problems. Installed a known good seagate drive, all problems stopped.

Since I was having some issues with my system, I just reinstalled W7 from scratched on my SSD. With this new install I decided to go the AHCI, UEFI, GPT route instead of MBR and IDE like on my previous install.

Everything installed smoothly. I took a look at my BIOS setting and I can see in my Boot options that my #1 boot option is set to "Windows Boot Manager". My SSD is #2 and my DVD drive is #3. I only have one system installed (W7) so I'm not dual booting.

When I change the boot order and set my SSD as #1, my computer won't boot and tells to select a drive with a bootable system. "Reboot and select proper boot device or Insert Boot Media in selected boot device and press any key"

Is this normal behavior?? If not, how do I fix this?

A:Why do I have to select the Windows Boot Manager in the BIOS to boot?

When you reinstalled Windows you should have disconnected the other drives and leave only your SSD connected as now you have your boot files on the other hard drive so either reinstall Windows disconnecting the other hard drives and reconnect when you're done or follow the suggestions in this thread

Finally, after being passed from one agent to another during some hours today, I was eventually forwarded to a 14th person at Dell, who was the right kind person to help me with my problem. Hurah!
But we could not find a solution.
During the call, I had to delete the Windows Boot Manager that figured in the sequence, and which was not working. And then to add it again.
So far so good.
I added WINDOWS BOOT MANAGER after clicking on $boot (after choosing one of my partitions).
But it then showed up as WINDOWS BOOT MANAG
I tried again Windows Boot Manager
which, again, came up as Windows Boot Manag
Two letters missing... So this is not working, and computer still doesn't boot into OS.
Any idea how to add Windows Boot Manager correctly?
by the way, I found this file bootsector.bak - is this of any use to restore my boot sector??
Would be great to get some help. I am on that issue full time since 3 days now, and can't even do my normal job.

Yesterday, after many, many problems with my computer, I finally decided to reinstall Windows 8.1 Pro onto my ASUS X200CA netbook. However, after backing up and reinstalling the OS, I found that when I tried to disable "Launch CSM" in my BIOS, all of my boot options would disappear and my laptop would continually boot into my BIOS. When I re-enabled "Launch CSM", the boot options would reappear - however, it had not included the "Option #1 - Windows Boot Manager" that I had seen in my other installation.

I searched around the forums for a bit and even tried some things that could possible alleviate my problem, but to no avail. Here's the situation:

My main pc was having problems...I would be playing a game, writing an email or something as simple as browsing the web and my pc would lag for 5-10 min or would just freeze up. I would try to reboot the pc and sometimes it would get to the windows loading screen and it would freeze or it would just get past the loading screen and just remain black (I could always get into BIOS though). One thing that would always work would be for me to shut the pc off for an hour and then reboot. Then it would run great for a while.

I decided to just reinstall Windows 7 Ultimate and start over fresh. After installing the OS, I started to reinstall old programs and low and behold my pc would freeze/lag again. Rebooting would result in the black screen/freeze also. So, what I did was take everything apart and put everything back together again. The only thing I changed out was the cpu cooler, because I figured it might be an overheating issue (the gpu was never hot). So, after installing everything back the way they were, I powered up and the real headache started.

Now nothing comes up on my screen and the power button on my monitor just blinks like it's in sleep mode (not detecting anything?), I also get no beeps but it does sound like it's trying to boot. All the power is running through the mb (led is on), all fans are going s... Read more

I'll try to give as much information as I can.
This morning I ran an Avast virus scan and it detected two files which it put in the "chest."  It suggested a reboot, and something about an additional scan.  I do not remember the files tagged nor the scan it suggested.  I rebooted since it all seemed reasonable.  Upon reboot, it never got to desktop.  It didn't get anywhere, splash screen, Windows logo, nothing.  After many minutes, I held the power button to manually shut down.  This has happened a few times in the last six months.  But it always worked again after turning back on (post manual power down).  But now it didn't.  I tried several times, same thing.  I even left it on for over an hour thinking maybe something is happening in the background, but nothing.  No clues or indications as to what is wrong.  Always a black screen.  No mouse cursor or anything.  Monitor says it isn't getting a signal.
I did research all day on the topic.  I tried getting to a "safe mode" or to BIOS by tapping function keys.  No avail.  I tried booting with the Windows 7 recovery DVD I got with the computer.  Nothing.  I tried unplugging the battery for 15 minutes to clear memory.  Nothing changed.  Tried replacing the battery.  No luck.  After unplugging and plugging back in the battery to clear memory, the problem seems worse, actually.  Now, shutting do...

A:Won't Boot, Black Screen, Can't get to BIOS

Hi everyone there!

I don't know if this is the right place, but I think so and I'll try.Well, I won't introduce myself, as I want to be quick.
Let's go to the problem. So I was using Windows 7 when I came out with the idea of installing Windows XP, as 7 was sucking my memory up (300 MB of my beloved 512 RAM). So I read a tut on how to install XP after 7 was installed, and after XP's first stage of setup, it told me to restart. But for my surprise it wouldn't boot (a screen appeared telling me BootMGR was corrupt). So I managed to get a Vista DVD (Not 7 cause I couldn't find it), and ran the Command Prompt. So I wrote what the tutorial told me to write:
-Bootrec.exe /fixMGR
-Bootrec.exe /fixBoot
It showed me up as the operation was successful, so I restarted my PC. Now, WTF, I can't get to 7 because a black screen (it was blank) stayed after 2nd Boot stage.
So I put the Vista DVD again on my drive and installed it over the partition where XP would have been. After installing everything I'd expect a Vista or 7 boot, but, again it wouldn't let me!
Now I got my PC ruined up, I cannot boot 7 from hard drive because of this. What shall I do? Is there a way I can get 7 back? Please help!!

Following this, Windows failed to reboot showing a WDF_Violation blue screen, a further boot resulted in a Cache rebuild screen followed by an Intel driver error. After repeating this cycle a couple of teams, I hard rebooted the PC.
Now, the computer boots to a black screen. I can see the backlight come on for a few seconds however there is no BIOS splash screen neither is there the usual beep when the pre-boot checks complete.
I have tried booting with a Windows 10 CD and from USB without success. I have also tried pressing the full range of function keys.
It is running Windows 10 and has been without issue for around 6 months until now.

Hi, everyone. I recently had a new computer built for me (http://pcpartpicker.com/p/svHXMp) but I've had an issue with actually getting it to load past BIOS over the past two weeks.

Currently, the system will boot to BIOS, as I don't have an operating system installed on my SSD, and then go to a black screen with a blinking cursor if I don't input any commands to take me to the status/options screens.

Yesterday, I tried installing Ubuntu on the computer just to see if I could get a working OS on it, but it went to the same black screen instead of loading the installer. I've looked in the options and the computer recognizes my HDD, SSD, and USB, and I've swapped the boot order around more times than I care to remember, but I honestly have no clue what's going on. Any help would be greatly appreciated!

A:BIOS loads to black screen; won't boot OS from USB

Background Info: The computer I am using I got from a relative who died. He had bought a HP computer with a Windows 7 Home Premium upgrade disc that he ran in order to upgrade from Vista to Windows 7. When we got the computer it still had all of his files and user account named Dave.

When I started using it, I left his files on there but deleted a lot of unnecessary programs I didn't want or need. I also renamed the user account from Dave to my name.....

Fast forward to the present. I got help from HP customer support last night to get a wireless printer we had boughten up and running and he said he cleaned up the registry to get rid of old printer files that were causing a fatal error loop during a printer install. It worked and I was able to successfully install the new printer.

After I restarted the computer and the boot manager screen came on it was missing an option from the list. Previously it said Windows Vista (Recovered) and also Windows 7 Home Premium (Recovered) both options would load Windows 7 though no matter which you choose. At this point the Windows 7 option was missing from the list and it just showed Vista. When you clicked Vista is just reverted to 7 though.

In an effort to fix this I put the Windows 7 Home Premium disc in and restarted the computer and then clicked on startup repair. It gave me a popup right away telling me there was a startup issue it needed to fix. I assumed it would fix the Windows 7 issue on the boot manager so I clicke... Read more

Sounds like you have a Dual Boot of two Windows 7's.

From the Win7 which works correctly, please post back a screenshot of your maximized full Disk mgmt drive map with listings, using the Snipping Tool in Start Menu. Attach file using Paper Clip in Reply box. Screen Shots

Type Disk Management in Start search box to get there.

We will help you get rid of the unneeded Dual Boot menu and second installation if there is one.

You can also use the Win7 Upgrade installation DVD to do a clean reinstall of Win7 without the HP factory bloatware or messed up Dual Boot if you want. Look over the steps which apply to you: Reinstalling Windows 7

I am building a new system.

Gigabyte MB GA-MA790GP-UD4H
AMD Phenom II F4 Quad core 3.0 MHZ
G-Skill 4GB DDR2
LITEON DVD RW (Redeployed from an older non-64 bit machine)

I am able to get the BIOS to post. It recognizes the HD as master on the SATA cable and it recognizes the DVD drive as master on the IDE channel.

When I save and exit BIOS, it goes into a loop of restarting with the startup beep, then reads "Verifying DMI data..." then restarts.

I am unable to get to a prompt for booting the Vista disk. I did get to a prompt by disconnecting the harddrive, but when Windows came up it when to a blank blue cloud screen.

I reconnected the harddrive and get the same loop restart result.

Any ideas would be greatly appreciated.

I've been experiencing a completely black screen after my BIOS loads. A Windows update hit my computer last night and since then, the OS completely fails to boot.

Both hard drives (system volume and storage) are present and accounted for in the BIOS.

I tried Startup Repair by booting with my Windows disc, but it detected no problems and told me that my OS boots perfectly. Also tried some method I found on a forum saying Startup Repair must be run three times, but I got the same result each time.

Next step was System Restore. I have tried restoring from several different restore points, but I get an error message each time. Something vague, along the lines of "System Restore has failed." This is pretty worrying.

I tried to "upgrade" my Windows installation from the disc, but the next screen said to restart, then boot into the OS, then "restart the upgrade." No use to me since I can't boot my OS at all.

Anything to do with Safe Mode isn't an option either, since there is absolutely nothing happening after my BIOS loads up. Just a completely black screen. No Windows logo. No blinking cursor. Nothing.

All I can think of now is backing up my personal files and reformatting/reinstalling Windows from scratch, but I really, really do not want to do that. Any help would be much appreciated!

EDIT: Forgot to mention, my computer has always had a habit of crashing/BSODing at the most inopportune times due to some crappy music hardware I own. Not reall... Read more

My laptop is a Acer aspire 5738z running windows 7 home premium 64 bit and my problem is my laptop will not start. When I turn my laptop on it starts to run like normal: GPU fan starts, Disk drive kicks in, and the LED for the on button is working but nothing on the screen. I've tried too do alt + f10 for a restore, nothing happened. I've also tried to plug it into a monitor and my tv. Before this occurred it had been turned off during boot (don't ask why, I cannot answer that) and I preceded to take it apart(to fix the overheating issue due to acer not putting fan holes on the bottom of the laptop ((thanks Acer -.-)) and I didn't realise something was wrong with it until I reassembled it and tried to turn it on. So I'm not sure whether is corrupt BIOS, a hardware problem, or corrupt MBR (my own personal diagnosis, don't know whether it's right or not). Also I have tried turning the laptop off taking the battery out letting the motherboard discharge then pressing the power button for a minute, leaving it for a minute, putting the charger in then turning it on.

Thanks. =]

A:Laptop wont boot Black screen no BIOS

You may need to take it apart again and make sure everything is connected properly. Did you follow steps to keep yourself grounded while working inside the system?
As you add and remove hardware, follow these steps for ESD safety:Shut down and turn off your computer.
Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
Once these steps have been followed, it is safe to remove and replace components within your computer.

I'm struggling to work this out - (Windows 7 32-bit on a HP pavilion dv2500) I rebooted about a month ago (a few days after upgrading from vista to 7, but maybe this is unrelated?), and there was just a black screen, no cursor blink, no bios, nothing, but the disc light is flashing, then Windows startup sound goes off, so it has booted after all. I tried attaching an old VGA monitor and sure enough there's my desktop. I close the lid in frustration and unplug the external monitor. When I open the lid again the display comes on this time but its in 1024x768 (not 1280x800), and when I try to readjust the resolution its just not available as an option - loads of other resolutions, but not 1280x800.

So, I install the latest nvidia driver, flash the bios with the latest version, restart, but still the same. Randomly once when I F10 into the boot menu (which is appearing on the external VGA), then do a save and restart from there, the laptop display came on again, boots into Windows fine, at the correct resolution. I use this for a month or so, it sleeps and resumes no problem (I didn't restart it), everything working as it should.

Then the latest windows update comes along and requires a reboot, and I'm back at the same point - if I don't connect the VGA external then I've got a blank screen (no backlight, nothing), even though windows has started. But if I connect the VGA, put it into sleep, disconnect the VGA, resume from sleep then I've at ... Read more

Hi all,
I have an HP Elitebook 9470m for work with Windows 7 pro installed. I would like to be able to boot a personal copy of windows 8 from my external usb 3.0 drive (western digital elements)

so i followed this tutorial:
How to Run a Portable Version of Windows from a USB Drive

and got windows 8 on my drive ok. Issue is im having really problems getting the option to boot from the drive to come up in boot options. Basically only the notebook hard drive and PXE are an option UNLESS i go into BIOS and mess about with changing boot settings to and from legacy to UEFI (with / without CSM) eventually on turning on and off it will give me the option to boot to my drive but its really hit and miss. when i get the option all boots into win8 no problem.

any ideas to get this to work better? i dont really know the settings im changing and i know messing about too much in BIOs is bad!

my external drive has 2 partitions, 1 for win8 and 1 for my other files both are NTFS. the laptop came with an internal mSATA which is all formatted to NTFS even system reserved. I tried creating a partition of FAT32 for boot and that hasn't helped. same behaviour.

any help or pointers would be really much appreciated!

It just says after eMachines pops up and then disappears the screen quickly says contact

You didnt need to DISABLE every boot option, just needed to put cd/dvd first boot.

Have you tried calling on the phone to talk to a tech?

If your not getting the first screen to enter bios, then this could mean bios is damaged,

you will need to send motherboard to emachines.

Take it that you already tried Esc, F2, F10, F12, Del, Ins, etc... repeatedly during boot up/splash screen.
If so, next I would shutdown the machine and hold down several keys at once and boot up.
The intent is to cause a keyboard error to force access to the BIOS. It may work.

Hi everyone. Please help out here. I have an HP Pavilion G6-1d40ca. It crashed the other day while I was using it, and when I restarted it, it went to BIOS update. It froze while updating, and died in itself (I think the battery died, it wasn't plugged in. I never knew about BIOS update, so I wasn't expecting for the battery to die during the update, so I didn't plug it in.) Second time, booted it up (it was plugged in this time), and went into BIOS update once again. All's good, was able to use the laptop for about five minutes, then it crashed once again. Now, when I boot it up, nothing comes up on the screen. No nothing. The power button is on, the wi-fi is on, the LED light is blinking non-stop, more than 6 times than what is referred to the HP website.

I tried doing the remove battery and adapter, press power button for 30 seconds, plug it in without the battery, but to no avail. I also did the whole win+B, but doesn't work either. I tried pressing f11, but nothing comes up on the screen. I don't remember where I put the recovery discs that came with the laptop. I thought I put it on the box together with recovery discs for our other computers at home, but I guess I didn't. The thing is, I don't know where to begin, since I don't have anything on the screen itself. Not even a start-up logo or something.

I only had this laptop for about 3 months, and looking at the other threads, it might be a hard drive failure problem. I could return it to HP, but was just wonderi... Read more

A:Failed BIOS update,HP pavilionG6 won't boot up and only black screen

Did you run a BIOS update, because it wouldn't restart into one. What exactly did the screen say that made you think it was a BIOS update being done without running it yourself (unheard of).

What LED light is blinking nonstop?

Can you boot into HP Factory Recovery: HP Recover Windows 7 Operating System Using HP Recovery - HP Customer Care (United States - English)

You can try these steps for Troubleshooting Windows 7 Failure to Boot which will tell you if you can boot a disk to do repairs. If so besides links to the Win7 installer to use for repairs, there are also links to HD and RAM bootable CD tests to check your hardware.

But if this cannot get traction quickly what I would do with such a new rig is call HP Tech Support and have them walk you through steps to determine if it should be returned or if there is a known issue.
