Is what gdisk says my computer looks like (well /dev/sda, but you know.) Anyway no matter which operating system I use etc every time cfdisk refuses to let me edit my hard drive why? It always returns an error which is Warning!! Unsupported GPT (GUID Partition Table) detected. Use GNU Parted. Anyway the command I am running is sudo cfdisk /dev/sda which I think is proper for editing the /dev/sda partitions. Anyway any idea as to how to stop this without completely reformatting my hard drive b/c I don't like gdisk that much.

@SamMercier: sorry, your edit clarified it. Simple solution: replace f with g and use cgdisk (answer edited too). –  izx Jul 29 '12 at 20:37
    
Thanks I that is what I was looking for. –  Sam Mercier Jul 29 '12 at 20:38

You appear to have a GPT partition table and cfdisk will NOT work with those (only MBR supported). Please use cgdisk instead :)

Normal usage of cgdisk on GPT hard disks

Just start it as sudo cgdisk, and you can interactively perform operations. If you have a desktop or X installed, a GUI alternative such as gparted may be preferable.

Sorry my first post was unclear I just edited it. Hopefully that will make my problem more clear. Okay thanks I am kind of new to partitioning in the command line. –  Sam Mercier Jul 29 '12 at 20:30
