DO NOT CONVERT. Just wipe the drive clear with DBAN or GPARTED and let your Windows installer do the partitioning. Partitioning before installing Windows can sabotage your work.

But as the installation begins, setup complains that it can only install Windows 7 onto a GDT bootable partition. My C drive partition is currently MBR.
I understand that the DOS utility DISKPART will convert MBR to GDT.
So I attempted to create a second partition D: 15GB and using Partition Wizard also set this new partition as Primary.
I then run up a DOS window as Admin, and at the command prompt did:
DISKPART select disk 0
DISKPART clean
I then got this error message:
Virtual Disk Service error:
Clean is not allowed on the disk containing the current book, system, pagefile, crashdump or hibernation volume.
Any clues please how to overcome this in order to convert the partition to GDT?
Thanks...
