When updating Windows 11 to the latest version using Windows Installation Assist option, after installing level 3 upto 77% progress, it pops up a window that "Window's couldn't update the system reserved partition". How can I resolve this?

    Please open an admin Command Prompt window (instead of PowerShell) and run these commands one by one:

    mountvol Y: /s

del  /q  Y:\EFI\Microsoft\Boot\Fonts\*.ttf

powershell -command "GCI Y:\  -File -Recurse | Sort Length -descending | Select FullName, Length, Mode -first 10"

dir Y:\

    Post the output here.
