Convert an MBR disk to a GPT disk

Overview

You can convert an MBR disk to GPT by restoring or cloning an MBR disk to an existing GPT disk. A GPT disk will have a small (128 MB) partition at the front of the disk. If you copy your source partition(s) to the free space after this partition then the target disk will retain its GPT state.
