To fix this you will need a Windows 11 install media drive and the machine in hand.
- Plug the install media into the machine and change the bios/uefi settings to boot from the flash drive.
- Once booted, click Next on the screen, then "Repair My Computer".
- Click Advanced Troubleshooting, then Command Prompt.
- Run the following commands in this order:
- bcdedit
- bootrec /fixboot - This will return with "Access is denied". This is normal
- bootsect /nt60 sys - This will update the boot code on all targeted volumes
- bootrec /fixboot - This will complete successfully
- bootrec /fixmbr - Same as above
- DISKPART
- list disk - Identify the OS Drive you're looking for
- select disk # - Select the disk you're needing to fix
