Could you share a photo of what you see on the screen?

If it is a EFI - GPT drive, @Celery already gave you the commands to fix it on post #14


Boot from a Win 10 or Win 11 USB installation drive and at the Windows Setup screen, press Shift+F10 simultaneously to open a command line prompt and type:

diskpart
List vol (identify the Windows partition letter X)
select volume X (replace X with the Windows partition letter found above)
active
exit
bcdboot X:\Windows /s X: /f BIOS (replace X with the Windows partition letter found above)
exit

or

If you can boot into Linux
Open your terminal and run
sudo update-grub
to scan for operating systems and rebuild your configuration file. It will make an option under Grub to boot Windows

List Vol:
Vol 0 C OS NTFS Partition 953GB Healthy
Vol 1 ESP Fat32 Partition 190MB Healthy Hidden
Vol 2 D BootDr Win1 NTFS Removable 14GB Healthy
Vol 3 E UEFI_NTFS FAT Removable 1039kb Healthy

(replace X with the Windows partition letter found above)
Vol 2 + Vol 3 Drive Letters D+E state "Removable" so they must be located on the Flashdrive

Vol 1 is Hidden and has no Drive Letter
Vol 0 is Drive Letter C, the traditional OS Drive Letter, and it states "OS"

It seems obvious that I should replace "X" with Drive Letter "C", but I'm going to ask anyway...
Should my next entry on the Command Line be "select volume C"?
