Debugging :: BIOS Corrupt / Error 0x000000f - UEFI Settings?
Nov 12, 2013
I have a Samsung Series 5, NP550, that was making me very happy until about a week ago when I accepted the Windows 8.1 upgrade that was pushed to me from Microsoft. After installing that, I had some misbehavior of my ethernet card, so I installed Samsung's Software Update to get new drivers and so forth. One thing I accepted was a BIOS update. After installing all the stuff, the PC began to tell me that my boot sector was bad, about every other startup, so I did a system restore back to the point before I installed all the software updates. I made the mistake which was to reset the BIOS to 'factory' settings - this wiped out the contents of my BOOT tab in the BIOS (P05something, which I guess is Phoenix... and UEFI). Up until then I could boot from a recovery USB, but now I cannot do that no matter what key I tap (F4, F8, F12...), I still get the same error:
0x000000f Your PC needs to be repaired - Tap F2 to enter UEFI settings.
If I cannot get past this with a bootable USB drive, how will having a recovery CDROM from Samsung (which is coming in the mail)? Either the BIOS is corrupt, or I need to find the mysterious setting that is disabling the whole thing. I can easily remove and slave my C drive to recover any files that I hadn't backed up - my fear now is that I won't even be able to recover because I have hosed the BIOS.
The only thing I have NOT done is pulled the battery and drained the CMOS battery so the BIOS forgets itself. Should I remove the hard drive and start the computer, so it forgets the hard drive, then put it back so that it treats the hard drive as a new system device? Should I throw the computer out the window?

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 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. 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?

I have Lenovo Essential G480 core i5 released in 2012 . In Bios settings it shows only "UEFI enable or disable " . I enabled it and installed Windows8 in uefi boot Using uefi enabled usb . I read on internet that Laptop manufacturers name appears instead of Windows 8 logo on uefi boot, it does not happen in my case also booting has gotten more slower .. and computer is not as smooth as it was before with old bios , it stuck sometimes now..i also checked my bios by "msinfo32" it shows my bios is UEFI... still its not like the real thing at all ...

Today I've had a bsod on Windows 8.1 pro 64 bit, I got this error pfn list corrupt and waited for the pc to restart and it didn't. I've turned off the pc by holding the power button for a couple of seconds, restarted it, now it doesn't boot. The lights on the motherboard light up but the cpu fan isn't running.

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

I upgraded my HP M7360N with a Pentium D 2.8 with 2gb of ram to Windows 8 and then to 8.1. It hasn't been too bad except for the video card driver, but wanted to put 2gb more of ram into it as it is a GeForce 6200 turbocache. I ordered 2 1GB pc4200 sticks which are the same as what I have in it. At first it wouldn't boot and had the ram replaced. It still didn't work and was about to send back for a refund but then put the 2 sticks in the original ram slots and it booted.
I put the original ram in the 2 slots that were originally empty and then got an ACPI_BIOS_ERROR and it said it was gathering info but it never left 0%. I am updating bios right now but the fixes listed on the update didn't say anything that I saw would be related. What can I do to try and get the ram to work.

On a new Win 8 laptop I can't boot from a USB flash drive or even a CD unless I turn off secure boot in the BIOS?
This surely can't be progress?

I have windows 8.1 installed on 120gb ssd. I also have a 1tb HDD too. So I was trying to install Hackintosh/Linux when I noticed that the System Reserved partition was on my HDD instead of the SSD. So, I used easybtc to migrate my boot files to my SSD. I deleted the system reserved partition. Now I want to convert my BIOS to UEFI. I have Z87 pro mobo.
I tried this tutorial: [URL] ....
But it seems to be geared at the C drive, where I don't have room for that 350mb as disk utility wont let me shrink it.
Edit: would downloading a third party partitioner, shrinking C about 350mb, or whatever is the minimum, and then use that new space as described in the guide work?

Just got my hands on a brand new ASUS K95VB notebook on behalf of a friend. I used a USB with Windows 8.1 on it in order to format the hard drive and install Windows. The hard drive is 3TB. I remember trying to install Windows using the UEFI option in the usb startup menu but that didnt work so I proceeded on the non-uefi option.
Now the problem is that only 2 TB are shown and the remaining 1 TB is shown only in device manager as not assigned...
If I understand correctly, the BIOS should be in UEFI mode and then the hard drive should be converted to GPT and then install Windows.
But, no option in BIOS for UEFI to be enabled whatsoever. What on earth should I do?

Right before I performed a clean install of Windows 8.1 x64 on my Inspiron 3520, I switched to the Legacy BIOS *facepalm*.
When I enter the legacy BIOS and enabled "secure boot", I performed a restart that gave the following message "internal hard disk drive not found, to resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 enter setup menu, F5 enter PSA". Of course, when I go back into the BIOS and disable secure boot, it reverts back to legacy and boots up Windows 8 just fine. What I'd like to know is, how can I revert back to UEFI so I can change the boot-up option and perform a clean install under UEFI.

On my computer there is a pre-installed Windows 8 which works fine for UEFI boot (Secure boot not necessary).
Now when I switch in UEFI setup at boot time the UEFI mode into the CSM (BIOS) mode and restart then Windows 8 is not starting any more.
As far as I find out an UEFI-based Windows 8 can only boot with UEFI mode enabled.
So my question is: Can I turn an existing UEFI based Windows 8 installation into an CSM/BIOS based installation (=a Win8 which boots successfully even when I enable CSM in UEFI setup) ?
If yes: How do I do that?

I cannot install windows 8 in BIOS or UEFI mode.
it's getting boot and install only in EFI mode. after trying to reinstall it won't allow me to select the disk partition, as it gave me the error "
Windows 8 cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks." i tried all the given solutions on GOogle. even i cannot recover or refresh using windows 8 environment. many times it gives me BSOD. cannot vonvert to MBR as it says it cannot be done on virtual HDD.
tried many things nothing works, need to install windows 8 after every 1 or 2weeks, many a times my BCD data gets corrupt, and windows wont start. Also tried many things to repair this, but only thing that works is reinstalling windows 8.
That gpt or MBR error was solved by selecting UEFI:CD drive. in boot options by pressing F12 after inserting the disk.
My system configuration:
System Info Utility version 1.0.0.2

I am trying to boot from USB in order to start using Ubuntu but my problem is that when I go to the advanced settings - troubleshoot - there is no UEFI Firmware Settings, which, from what I have gathered is necessary to be able to boot Ubuntu from my USB flash drive. So far the solution that most people have is that there is no UEFI on that particular computer/type of windows 8, and on the startup screen to press f2, f11, esc, etc but there is no indicator as to what key is is on the ACER splash screen, similar to this. scn101.jpg
Therefor, I cannot get into BIOS?

My bios shows uefi boot option but no uefi shell... I enabled uefi boot option and booted my dvd it asked me to partition my hd using a GPT format... I even did so so... but when I run
Code:
bcdedit /enum
In elevated command prompt it shows me this
Code:
Windows Boot Manager
--------------------
identifier {bootmgr}
device partition=DeviceHarddiskVolume1
description Windows Boot Manager
[Code] .....
The bold line means my system does not boot from efi... isn't it?

Have a toshiba laptop with the UEFI encrypted windows 8 key. The hard drive was broken as it was dropped. No sticker on the bottom as is now microsoft policy. Download of the windows install needs the windows key. Cant get it as it's encrypted. Found generic windows 8.1 keys which worked but it said it was the wrong key for those installs. Generic windows 8 keys don't work for the download. Going around in circles and not sure what to do.

Question: How would you approach this migration?
I just bought a copy of Acronis True Image 2013 with Plus Pack. It appears that this is all I need as True Image will install the new motherboard drivers as part of the migration process. But do I stay with MBR or move to GPT?
Presently both Win7 (on a 120GB SSD drive) and Windows 8 (on a different 120GB SSD drive) are both MBR format. I don't want to start over from scratch. That's why I bought the Acronis 2013 with Plus Pack.

I'm trying to install windows 8.1 to an external hard disk (solid state drive 128 gb usb3).
I've tried easyUFEY WinToUS creator and AOMEI Partition Assistant Standard(Windows to go) with no luck.
My bios has UEFI option only(no legacy). On my old laptop it works just fine(I had the legacy option) but now, I cannot do that anymore.
I'm pretty sure it's a bios boot issue and I don't know how to fix it. I've tried using GPT partition instead MBR, Still nothing.
The laptop is a sony vaio duo 13 and I have no legacy option in bios

So, I got a Inspiron 3537 i5. Nice laptop for it's price. Downloaded all the manuals, made my recovery DVDs. All was well in my world.
First thing I noticed is that there is no info in the manuals for tweaking the BIOS and since it is my first experience with a UEFI bios I was a bit disappointed. Is there a manual available for it?
Next I upgraded ATI Drivers to 13.12. I am an old user who always knew that updates were usually a good thing to do. Got in the same problem as many others with PC screen not waking up from sleep.
Thought I would do a recovery from the disk, but after trying various combinations (Ctl+F11, F8, F12 etc) I couldn't find a way to boot in the Recovery console. I did the recovery from my DVD and the laptop works fine.
How to add in UEFI bios a boot option to the Recovery partition? I undersstand that I have to create a new boot option using "Add boot option" and the two options available are to boot to the 1st (windows EFI) or 2nd (recovery partition), but the path for the recovery efi file to be loaded is unknown (+ you can't have access to the recovery partition to see the contents of it from windows).

MDL project. There are a few BIOS dumping tools out there but none specific to this task as yet.
The image could then be used in replacement for the standard W8 flag on systems without UEFI.

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 recently installed windows 8 on my MacBookPro with UEFI support, but I can't enable audio. I know that apple use BIOS emulation for windows and the assign different Hardware ID's for devices.
With BIOS emulation ID is:
HDAUDIOFUNC_01&VEN_1013&DEV_4206&SUBSYS_106B5300&REV_1003
Without emulation ID is:
PCIVEN_8086&DEV_1E20&SUBSYS_72708086&REV_04.
I tried changing inf file and it detected the required audio card driver, but it shows that device cannot start. It's Cirrus Audio CS4206B (AB83) sound card, but without emulation it shows it as intel audio card. It would be easier to get back to bootcamp, but I really want to make this work.

I am having a perplexing issue after doing a clean install of Windows 8 on a 256GB SSD where I can not get into the "UEFI Firmware Settings" Tile in Advanced Options. Basically, when trying to enter the EFI/BIOS via: Settings in Charms / PC Settings / General / Advanced Startup / Restart Now / Troubleshoot / Advanced optons I do not see the "UEFI Firmware Settings" tile to get into the UEFI/BIOS!
My machine (which only has (1) hard drive) is an Asus N56VZ and came pre-installed with Windows 8 on the factory 750GB 7200rpm HDD. I cleanly reinstalled the OS on to a new 256GB SSD via an OEM copy on a disc and all seemed basically OK except that sometimes when getting to the Login screen it would freeze and the cursor would not be flashing, I could not enter my password nor shut down via the power icon on the bottom left of the screen. I would then have to hold down the power button to shut off the machine. This freezing of the login screen would be intermitent where most of the time I could enter my password but maybe 20% or so of the time I could not log in.
Due to that bug I decided to securely erase the SSD and once again reinstall Windows 8 and now I have this issue where in the Advanced Options menu there is only (5) tiles/options present and not the usual (6) as the "UEFI Firmware Settings" functionality is now missing

My computer is so messed up Version 8.1 . I first noticed that I had a problem with Kaspersky. It said my license was unable to verify and to update data base to solve. It wont let me update. In fact it wont even let me uninstall, and secondly I cant download ANYTHING off the internet. My main problem is OFFICE keeps freezing and I need that program it also says there is a problem with my license and I have not been able to fix it it just freezes. So I thought I will download open office, but as I mentioned I cant download anything when I click run nothing happens when I click save it says corrupt or unreadable file. I thought no problem I will just hit F2 (yes I have tried hitting every single key after this and nothing) and enter bios screen and recover from my USB but do you think F2 (or any other key takes takes me there, no. Products like Kaspersky, Office, I have paid for etc say they are unlicensed which they are not. Anything I try to download, anything, like a new virus program will not work. I can't download, I cant even get into Change my PC settings it just freezes when I click this. I have had people try and trouble shoot this, Kaspersky has not gotten back to me and everyone is telling me stuff I cant do. I cant download, I cant access bios, I cant even access Change my PC settings. Ready to hear all the generic "it should" or "you should be able to"
