    The 1st part ran fine.

    Please run:

    • diskpart
    • sel disk 0
    • sel part 3
    • set id=07 override
    • exit

    Post the output.

    Post screenshot of Disk Management.

    Hmm. You may have to replace the disk, I think.

    Now that we've moved Winre to the OS partition, let's test our luck again. If setup runs fine, that would be great. Else, the disk needs replacement.

    Please insert the USB setup disk and run "setup.exe".
