Error Code: 0xc0000034 in Windows 8 - Boot Configuration Data file missing required information

Anonymous

I have Dell Inspiron 14z Ultrabook and recently received this error message after having no previous problems with the laptop.  Dell tech support ran me through hard drive tests and no problems were found.  I was told the only way to fix this issue is to reinstall the Operating System, which will cause me to lose all my files and applications I have installed.

Is there any other way to fix this problem so that I will not lose everything?  And how do I prevent this issue from happening again?

Very disappointed!

Hi,

Thank you for posting the query in Microsoft Community and we are glad to help you.

As per the issue, you get an error message “boot configuration data file is missing some required information” along with the error code “0xc0000034” when you boot to the computer.

I would like to gather some information on this issue to get a clear picture:

Did you make any hardware or software changes to the computer prior to this issue?

Perhaps, Windows boot files might be missing which are important to boot into the computer.

Let’s try Automatic Repair for Windows 8 on the computer and check if it can resolve the issue.

You may follow the methods:

h) Windows 8 will look for problems on hard drive(s) and verify that all required files are intact.

Method 2: If automatic repair doesn’t help to repair the startup files, you may try to repair them using these commands through Command Prompt under Advance Options.

Refer to the steps:

a) After you boot your computer using Windows 8 DVDor System Repair Disc, a black screen appears with gray text "Press any key to boot from CD or DVD". Press any key.

    I wonder where should I post my article, but you would find where I post ;-)

    Hi,

    I have experienced the same trouble as you had and I also would like to avoid

    re-installing windows. So I tried to search informations for fix this problem

    and I got it.

    Apparentry, why we could not fix the problem by typing bootrec /rebuildbcd is

     because we have confused our environment about system, more succinctly, whether

     you use legacy BIOS/MBR system or newer UEFI/GPT system.

    Current manufacturer shipping there Windows8 PC product as UEFI/GPT system, or if you had

    installed your windows8 on UEFI/GPT, once corrupted your PC, you should fix

     it in another way from BIOS/MBR system.

    If you could not boot your UEFI system, (this means also you could not fix it

     by windows' Automatic Repair) you could fix it by these method.

    *Here to assume that disk 0 is a booting device.

    a) After you boot your computer using Windows 8 DVD or System Repair Disc, a black screen

    appears with gray text "Press any key to boot from CD or DVD". Press any key.

    b) Select the correct time and Keyboard type.

    c) Click Repair your computer in the lower left corner.

    d) Select Troubleshoot from Choose an option screen.

    e) Click Advanced options in Troubleshoot screen.

    f) Click on C ommand Prompt.

    g) Type these following commands and hit enter after each line of command:

    "#" is an instruction comment so not to type it ;-)

    to execute diskpart program

    diskpart

    DISKPART> list disk

    DISKPART> select disk 0

    DISKPART> list volume

    find your system partition with fat32 file system. Here to assume it as volume 2.

    DISKPART> select volume 2

    To assign drive letter.

    If you want to remove drive letter, use remove command.

    DISKPART> assign letter=b:

    To terminate diskpart command.

    DISKPART> exit

    Now, you sould move to b:\EFI\Microsoft\Boot, as windows stores BCD in this folder.

    *cd /d b:\EFI\Microsoft\Boot*

    this is not necessary.

    ren BCD BCD.bak

    To write a new bootsector on your system partition.

    bootrec /fixboot

    If your windows running, you should do from here.

    To create BCD store. "/f ALL" is to update BIOS setting including UEFI firmware/NVRAM.

    Replace "ja-JP" with your language or remove "/l" option if you use English, of course.

    It might be sense only typing "bcdboot c:\Windows".

    bcdboot c:\Windows /l ja-JP /s b: /f ALL

    That's that. Booting information of your PC has been written over.

    Let's reboot and see whether it go fine or not!

    Thank you very much 

    It solve my priblem with mi Windows 10 in a Lenovo PC

    I know this is an old post, but it just solved my boot issue with Windows 10 after trying every other solution I could find (including those from MS) - thank you so much, if you're still listening!
