Understanding BCD Errors
To fix BCD errors, you can use the Windows installation media to access the Command Prompt. Once in the Command Prompt, you can use the bootrec tool to rebuild the BCD file.
It’s important to understand the different BCD error messages and their meanings, as this will help in troubleshooting the issue. Some common BCD error messages include “File: \Boot\BCD”, “Error code: 0xc0000034”, and “Error code: 0xc000000f”.
If you are unable to fix the BCD error using the bootrec tool, you may need to use third-party software or seek professional help for data recovery.
Understanding BCD errors and how to fix them is essential for ensuring the smooth operation of your Windows operating system.
Data Recovery from BCD Issues
If you are facing BCD issues and need to recover your data, follow these steps:
First, create a bootable USB flash drive or CD/DVD using a Windows installation media.
Insert the bootable USB or CD/DVD into your computer and restart it.
Access the BIOS or UEFI settings by pressing the appropriate key (usually F2, F12, ESC, or DEL) during startup.
In the BIOS or UEFI settings, set the boot order to prioritize the USB or CD/DVD drive.
Save the changes and exit the BIOS or UEFI settings.
Restart your computer, and it should boot from the USB or CD/DVD drive.
Choose the option to repair your computer from the Windows installation media.
Navigate to Troubleshoot > Advanced options > Command Prompt.
In the Command Prompt, use the bootrec command to rebuild the BCD. Type the following commands one by one and press Enter after each one: bootrec /fixmbr, bootrec /fixboot, bootrec /rebuildbcd.
After executing these commands, restart your computer and remove the USB or CD/DVD drive.
Your computer should now boot normally, and you should be able to access your data without any BCD issues.
Automatic Startup Repair Solutions
If you’re experiencing the “Windows Boot Configuration Data File Is Missing” error, there are a few automatic startup repair solutions you can try to fix the issue. First, try using the Windows installation disc or USB flash drive to access the Windows Recovery Environment.
Once you’re in the Windows Recovery Environment, select “Troubleshoot” and then “Advanced options.” From there, choose “Startup Repair” and let the automatic repair process run. This will attempt to fix any issues with the boot configuration data file.
If the automatic startup repair doesn’t work, you can also try using the Command Prompt in the Windows Recovery Environment. Enter the following command: bootrec /rebuildbcd and press Enter. This will attempt to rebuild the boot configuration data file.
If you’re still unable to fix the issue with the automatic startup repair solutions, you may need to consider other troubleshooting methods or seek professional help.
Rebuilding BCD with Command Line Tools
To rebuild BCD with command line tools, you can use the Windows installation media. Start by inserting the bootable USB or DVD and restart your computer. Boot from the installation media by selecting the appropriate boot device or changing the boot order in the BIOS settings.
Once the Windows Setup screen appears, press Shift + F10 to open the command prompt. Type “bootrec /rebuildbcd” and press Enter. This command will scan for Windows installations on your hard drive and rebuild the BCD configuration.
If the command finds any Windows installations, it will ask you if you want to add them to the boot list. Type “Y” for yes and press Enter. After the process is complete, type “exit” and press Enter to close the command prompt.
Finally, remove the installation media and restart your computer. Your BCD should now be rebuilt, and the “Windows Boot Configuration Data File Is Missing” error should be resolved.

Creating a New BCD File
To create a new BCD file, you will need to first access the Windows Recovery Environment. You can do this by inserting your Windows installation media and restarting your computer. When the Windows Setup screen appears, press Shift + F10 to open a Command Prompt window.
Once the Command Prompt window is open, type the following commands:
