So I formatted a 250gig drive with an sp0 version of XP Pro, naturally it only recognized ~130gigs. I got around that problem by formatting the remaining space with an sp2 version of xp home, then booting up the pro partition and formatting the home partition from within windows. The problem is that during startup the computer still sees two operating systems - XP home and XP pro. If you don't select XP pro in ~2 seconds, it tries to boot xp home and fails because the operating system doesn't actually exist. I tried messing around with the bios, even reset the CMOS with the jumper. Theres data on the partitions so I didn't want to reformat anything. Any suggestions?
