GPT is not a thing, a file or anything. It is a partitioning scheme.
It is an alternative to MBR, the traditional PC disk partitioning
scheme.

As far as I know, there is no way to change a GPT-partitioned disk
into an MBR-partitioned one. You need to totally erase the disk and
repartition it. I could be wrong on this, though.

E.g.
http://www.sevenforums.com/tutorials/26203-convert-gpt-disk-mbr-disk.html
 - note that this appears to me to be destructive; it removes all
partitions, as I understand it.
