Windows 10: “We couldn’t update system reserved partition” error installing Windows 10 cannot partition...

Cannot download Windows 11 due to this error, already tried deleting fonts but now I cant even access Y: anymore. And using mountvol now has an error ''The parameter is incorrect''Tried using this solution: Search for cmd. Press-and-hold or right-click on Command Prompt in the results, and select Run as administrator.At the command prompt, type mountvol y: /s and then hit Enter. This will add the Y: drive letter to access the System Partition.Switch to the Y drive by typing Y: and press Enter. Then, navigate to the Fonts folder by typing cd EFI\Microsoft\Boot\Font
