Fix Boot Record in Windows 11 - just for your general infoit was very easy in Windows 7 with bootrec.exe (/fixboot and /fixmbr), but I don't know if that is available with more modern Windows.
The next step is to go to the EFI partition and fix the boot record with the help of these commands.
ren BCD BCD.bak
bcdboot C:\Windows /l en-us /s x: /f ALL
Now reboot - done
