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.

      No luck. ChkDsk reported no errors.
      Still error 0x571

      Btw. I never saw 0x57 - only 0x571

        Sorry - typo on my part. 0x571 is what I meant to type. What make/model is the system and how was it built? If I had to guess, it is having an issue with the third partition. Type 39 is Bell Labs partition type.
