Understanding EFI Boot BCD Error

The EFI Microsoft Boot BCD 0xc00000f Windows 10 Error can be frustrating, but there are steps you can take to fix it. First, try booting from a Windows 10 installation USB flash drive. Once you’re in the Windows Setup, select “Repair your computer” and then “Troubleshoot.” From there, choose “Command Prompt” to access the command-line interface.

If none of these solutions work, you may need to check your hard disk or solid-state drive for errors. Open Command Prompt as an administrator and type “chkdsk /f C:” (replace “C” with the correct drive letter) and press Enter. Allow the scan to complete and follow any instructions given.

  • Corrupted Boot Configuration Data (BCD) files: This is a common cause of the error code 0xc00000f in Windows 10. The BCD files store important boot configuration settings, and if they become corrupted, the system may fail to start properly.
