    Angry Win 7 -> 10 Upgrade stuck in loop UNMOUNTABLE_BOOT_VOLUME

    Dear Masters of the Universe

    I'm kind of stuck with an upgrade. I built a PC for a friend, and they foolishly accepted the Windows 10 Upgrade offer, and now appear to have a Brick, rather than a PC.

    They're entirely non-computer literate, thus I can understand being conned into selecting the upgrade when offered so forcefully by M$

    System was built on an Asus MoBo with a SSD boot drive, and Seagate Data HDD. Originally Windows 7-64 HP installed.

    System appears to have corrupted the SSD somehow.

    Booting leads to a BSOD offering to restart the PC automatically, then after a huge delay, a screen with the advanced recovery options.

    I've tried to recover the boot, reset the PC etc. and now through the Command line I've checked the MBR using BootRec /RebuildBCD. Still no go. Bootrec /ScanOs reports Zero OS found which is obviously very worrying.

    I'm at the point of trying to reinstall Windows 7-64 HP from the original disks, and hope that I can recover the data files from the disks directly (User did not back-up!)

    Can anyone with experience of Windows 10 upgrade suggest any other route before I "Drop the big one!"

    Many thanks for any advice,
    D.

    Connect the affected HDDs/SSDs to another PC and see if you can access them to copy user's files to an accessible disk.

    Once you have secured the user's files you can try booting from a install DVD and re-installing.

    Hi Coochin,

    Many thanks but I was hoping to avoid pulling the PC apart to rescue the situation. Do you have any suggestion for an in situ recovery?

    Best regards,
    D.
