With UEFI, the EFI boot files cannot be rebuilt directly via BootRec /FixBoot unless the EFI partition is mounted and entered first (see Steps 2 & 5), otherwise an Access Denied error will occur; instead, once the EFI partition is mounted at Y: via DiskPart: BcdBoot C:\Windows /s Y: /f UEFI (the OS partition is normally not C: in WinPE/WinRE). Once done, resolve remaining boot issues via: BootRec /FixMBR && BootRec /RebuildBCD and reboot, even if no Windows installations are found.

| Jun 30 at 21:05 | comment | added | Ramhound | You deleted the partition (EFI) with the boot configuration data; the commands you ran require that data to exist so it can be detected. Had you not created new partitions, you might have been able to detect the deleted partitions. Your actions have made that now impossible. If you don't care about the Windows partition, you should just reinstall Windows. Why are you recovering two partitions that would only be required if you were trying to boot into Windows? | |
