Bluecsreen on booting. Error code: 0xc0000034 the boot configuration data file is missing some required information.

Hi Nathan,

The error message states that some of the boot configuration data is missing. The boot configuration data file holds all the required information for Windows to boot. If this file is corrupt or if some file is missing, Windows will fail to boot. In this case, we need to repair the Boot files or rebuild the boot files again.

You will need a Windows 8 installation disc to repair the boot files without affecting your personal files. If you don’t have a Windows 8 disc, I would suggest you to download the Windows 8 installation files from another computer through this link and choose to create an installation media when the upgrade assistant prompts.

After you have a Windows 8 installation disc, follow these steps:

1. When your computer starts, wait for the manufacturer logo to check the option for boot menu, it will usually be F12.
2. The boot menu key might differ with each manufacturer. If you are unable to find the boot menu key, you may refer the user manual.
3. Restart the computer, when the manufacturer's logo is displayed, keep pressing the Boot menu option key to enter the boot menu and change the boot option to CD\DVD ROM.
4. After you boot your computer using Windows DVD or System Repair Disc, a black screen appears with gray text "Press any key to boot from CD or DVD". Press any key.
5. Select the correct time and Keyboard type.
6. Click Repair your computer in the lower left corner
7. Click on Troubleshooting, advanced option and then click Automatic repair.

If the Automatic repair didn’t fix the issue, then you will have to manually fix the boot files from the command prompt. Follow the same steps as explained above to access the Windows recovery environment.  Once you are in the ‘troubleshoot’ screen, follow these steps:

1. Click on ‘Advanced options’ and then click on ‘Command prompt’.
2. Now, type the following commands in the order in which they are presented. Press ENTER after each command.

Bcdedit /export C:\BCD_Backup

ren c:\boot\bcd bcd.old

Bootrec /rebuildbcd

Try these steps and let us know the results.

Thanks for the reply. I've gone for the manual option with cmd promt, here are my results:

Hi Nathan,

I apologize for the delay in responding. Did you try the Automatic repair? What were the results?

If the issue persists, I would suggest you to perform a system refresh. Refer to the section ‘Refresh your PC without affecting your files’ in this article:

Note: If you upgraded your PC from Windows 8 to Windows 8.1 and your PC has a Windows 8 recovery partition, resetting your PC will restore Windows 8. You’ll need to upgrade to Windows 8.1 after the reset has finished. All your personal files will be deleted and your settings will be reset. All applications that you've installed will be removed. Only the applications that came with your PC will be reinstalled.
