I have a Macbook Pro model Mac2,2, and am unable to install Snow Leopard from the DVD I recently purchased. In order to accommodate the new OS, I upgraded the HD to a 320GB drive and reformatted it after backing everything up on a 500GB external drive. I also replaced the optical drive that wasn't working. No matter what I do during the installation attempt, I get to a screen that wants me to "...repartition this disk using 'GUID Partition Table.'" I have no idea what this means and, anyway, I don't see any option for choosing "GUID Partition Table." Can someone please help?
