    Any back-ups of your data? Try to UNFORMAT the drive first, to retrieve your data!

    Free Unformat Windows 10 Hard Disk Drive – EaseUS

    Good Luck!

    Cheers

    Unformat utilities are much like undelete ones, they are no guarantee of success.

    @IT101 you say you are unable to install Windows. Is it giving you any errors?

    Get someone else to install the software and connect the drive to it. Try doing an unformat is OP's best FIRST shot.

    Before accessing the drive with whatever, OP should first make sure to safeguard the data!

    Thanks for the help but I had alredy seen that and the problem is while selecting upgrade option it says'The computer started using the windows installation media and needs to be restarted.'

    And while selecting custom(advanced) it says ' The windows cant install on this disk. The disk has an MBR partition table . On EFI systems , windows can only be installed to GPT disks.
