Do exactly as you are instructed here. Use parted. fdisk doesn't support GPT partition tables, only MS-DOS tables. # parted /dev/sda GNU Parted 2.3 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) [] Now, type "help" if you are stumped. Or perhaps "man parted". Or even use gparted since that's the graphical version and much easier to drive.
