I have a macbookpro that wont boot properly. I've tried resetting the PRAM (holding down option - alt - P - R), but it doesn't work, it gets halfway through the boot process and says "You need to restart your computer" in several languages.

Recently I downloaded a USB Key compatible Linux OS. This USB Key works as a boot loader on Windows machines, but on OSX it can only find the Harddrive partitions when I go into the boot loader menu (holding down Option on startup). I am assuming it is because it is formatted as FAT32, and not GUID Table.

I believe my CD drive is also bust, it hasn't worked in a long time.

I don't have another Mac computer, so is there a way I can format the USB key as GUID Partition from a windows 7 machine?
