I need to burn both Windows XP and Ubuntu Linux on 2 disks (can't chose between ) so I can fix my rather corrupted hard drive but I have no clue what kind of disks to get. So can you tell me the best type to use. Example: dvd-r or dvd rw, or some cd thing. And of course the type has to be purchasable in a 1GB + size. I have no clue what to get.
