Fix: We couldn’t update system reserved partition

If you encounter the "We couldn’t update system reserved partition" error while trying to update Windows 11 to version 24H2, you can try the following PowerShell fix.

This solution is based on guidance from the Microsoft Support article titled "We couldn’t update system reserved partition" error when installing Windows 10.

$Volume = (Get-Volume -FriendlyName SYSTEM -ea SilentlyContinue).Path
if ($Volume) {
    Get-ChildItem -literalpath "$($Volume)EFI\Microsoft\Boot\Fonts\" -File *.ttf | remove-item -force
    Get-Item -literalpath "$($Volume)EFI\HP\" | remove-item -force -recurse
}

Warning: Proceed at your own risk!

The script retrieves the "Volume GUID Path" of the "SYSTEM" partition and deletes all .ttf font files from the EFI\Microsoft\Boot\Fonts\ directory.
