Not sure I can remember for sure but on PM desktop choose Partition Editor, when that opens select Gparted option then Device then Create new Partition table. Next window choose ERASE then in next window select GPT from the drop down menu then hit Apply, close everything and that's it.

Thanks, if anyone in the future googles for MBR to GPT conversion, and lands on your thread, they will have a guide ready for them.

I never thought about that, hope I have remembered the step by step instructions accurately but if not, it would only be off my maybe one minor step.

Converting on a clean drive can be done with GParted, Partition Wizard by Minitools, or diskpart

 

With Gparted the device you wish to be GPT is selected in the upper right dropdown box.

Next would be to create a new partition table as GPT that deletes all data on the drive if present.

 

In the menu bar select Device > Create New Partition Table. Select Advanced and then GPT in the dropdown box.

Partition Wizard can do this on a non system drive without data loss but the data should be backed up first as a precaution. The new version 10 is supposed to be able to convert a MBR system disk to GPT.

 

https://www.partitionwizard.com/help/convert-MBR-disk-to-GPT-disk.html

 

Note: A drive can be converted to GPT using diskpart. Using this method, like Gparted will remove all data on the disk.

 

Boot the Windows install disk. At the screen that asks for language press Shift + F10 to open a command prompt.

 

Type the following commands at the command prompt

 

diskpart               Opens a diskpart prompt window

list disk

select disk X        Where X is the disk Windows will be installed to, usually 0

clean                   Deletes all existing partitions on the disk

convert GPT        Creates a GPT disk partition table

exit

exit

 

Hope this helps.
