    There is a partition on the disk MBR2GPT doesn't like. Try running the following diskpart commands:

    DISKPART> select disk 0

    DISKPART> list partition

    .

    .

    .

    DISKPART> select partition 1

    DISKPART> detail partition

    .

    .

    .

    (repeat for each partition)

     

    You should be able to see which one is causing issues.

      Mike, I hope you will spend a few minuttes looking over this, as I can't figure it out on my own.

      Is the attached information sufficient?

       

      Thanks in advance.

        Error 0x0000057 means: The disk structure is corrupted and unreadable.

         

        Try running chkdsk and see if it finds anything wrong with the disk.
