    Hi all,

    Has anyone else successfully update a Windows 11 VM to 22H2?

    I have tried to update twice now but both times I get a BSOD shortly after the restart with a message saying "UNMOUNTABLE_BOOT_VOLUME". It then restarts again but eventually throws me into the Windows RE.

    Luckily I took a snapshot beforehand.

    On the first attempt I just restored from the snapshot, but on the second attempt I let it roll back via Windows RE and upon logging in I was greeted with a message saying:

    "We couldn't install Windows 11
    We've set your PC back to the way it was right before you started installing Windows 11.
    0xC1900101 - 0x20017
    The installation failed in the SAFE_OS phase with an error during BOOT operation"

    According to the Microsoft troubleshooting page...

    0xC1900101 0x20017 - A driver has caused a problem.

    This leads me to believe it may be Parallels related.

    Any help or advice would be greatly appreciated.
