The MBR stands for Master Boot Record and GPT stands for GUID Partition Table. The Master Boot Record record cannot reference more than 2TB of drive space. Although the limit of the GPT is still not known , ....Window7 has no problems reading the GPT boot loader so yes, GPT is a bootable partition format for you
When loading the OS, you get to a point where you will be asked Do you want to install on this partition (drive) instead of clicking yes/go....click format drive.......this will give you the option you're after of NTFS or GPT file partition format.........enjoy
