    If you have a Windows 10 installation media then boot with that and try a repair install.

    Else, you may create a bootable device from here:

    1)Indicate whether the computer no longer boots to Windows or whether it may boot to Windows

    2)Find one or two flash drives that you can format

    3)Find a working Windows computer

    4)On the working Windows computer create a bootable Sea Tools flash drive

    5)Move the bootable Sea Tools flash drive to the problematic computer and boot to the flash drive

    6)Run the Sea Tools bootable Long Generic Test > take pictures > post images or share links into this thread using one drive, drop box, or google drive

    7)If the disk drive fails the Sea Tools Long Generic test then backup files and replace the disk drive
