In addition to the other comments (I've never tried converting..mainly because all my systems boot from SSD), you'll need to make sure that your system is UEFI in order to boot a GPT disk.

It's Win7 x64, so it works fine, but when I clone, I only get a 2TB partition (of course) because it's MBR rather than GPT. I know I can convert to GPT without losing data using Partition Wizard, but PW tells me that if I do this, it won't be bootable. How do I make it bootable afterwards? T
