How to Fix It
1
Boot from a Windows installation USB, select 'Repair your computer' > Troubleshoot > Startup Repair — try this first as it often fixes BCD issues automatically
2
If Startup Repair fails, go to Troubleshoot > Command Prompt
3
Run: bootrec /rebuildbcd — when prompted, press 'Y' to add the installation to the boot list
4
If that fails, delete and rebuild BCD: bcdedit /export C:\BCD_Backup then: ren C:\boot\bcd bcd.old then: bootrec /rebuildbcd
5
For UEFI systems: run diskpart > list vol to find the EFI partition (usually FAT32, 100-500MB), assign it a letter, then: bcdboot C:\Windows /s [EFI letter]: /f UEFI
6
If all else fails, verify the Windows partition exists and is healthy with: chkdsk C: /f
