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:

Method 1: Booting to Recovery Environment with Windows 8 installation media.

Please follow the steps given below. Insert the Windows 8 installation DVD in the DVD ROM and restart your computer.

d) Select Troubleshoot from Choose an option screen.

e) Click Advanced options in Troubleshoot screen.

f) Click Automatic Repair from Advanced Options screen.

g) Next, choose the operating system by clicking on its button.

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.

Hi,

Yesterday I just solved my problem. My problem is that the OS volume became hidde... Hope my solution can be useful for you guys.

The first steps are as Microsoft guy said:

a) After you boot your computer using Windows 8 DVDor System RepairDisc, 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 computerin the lower left corner.

d) Select Troubleshootfrom Choose an optionscreen.

e) Click Advanced optionsin Troubleshoot screen.

f) Click on command Prompt.

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

>diskpart

>list disk

>select disk 0

>list volume // here you need to check the system volume status, if it was hidden, like mine, please follow the following guide; if your system volume was normal, please follow Microsoft guys' solution. If microsoft guys' solution cannot work, please skip this part and go to part II to fix the boot problem.

>list partition

>select partition N // here you need to use your system partition number to replace N.

>help set

>set id=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 // you can copy that from help set, someone said set id=07 override can work as well, but not for me...

>list volume // check system volume status, we can assume that it was not hidden anymore. following comments is to set your system volume to c:

>select volume N // N is your system volume number

>assign letter=c:

Part II : Then, you can follow the this guy's solution to make a new boot file

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

Then you need to finish the last part, as Microsoft guy wrote:

Bootrec /fixmbr

Bootrec /fixboot

Bootrec /scanos

Bootrec /rebuildbcd

Good luck all!
