Note! This function is available for Basic MBR Hard Disks only. Dynamic MBR Hard Disks can not be converted. The last-mentioned may first be converted to a Basic Disk (“Convert Dynamic to Basic”), then converted to GPT in a second step.

Typical layout of a MBR Hard Disk:

Launch the program and switch to the Advanced User Interface by clicking on the Full Scale Launcher or Advanced User Interface link in Express Mode.
Right click on the Basic MBR Hard Disk in the Disk Map, then select “Convert to GPT hard disk”. Please make sure to click outside the partitions to get the hard disk context menu.
Now you will see the warning visible in the screenshot below. If you don’t have an OS on the disk and you’re sure you want to execute the conversion click “Yes” and then “Apply”.

Note! Windows has different boot configurations for MBR and GPT Hard Disks. Using this option for a disk with an installed OS will leave the OS unbootable!
