So I'm able to partition, and it would seem install Windows XP Pro on my MB. But when I get to the Formatting the Windows Partition part of the Boot Camp guide I get a Disk Error every time. Do I HAVE to slipstream in order for this to work or are there any other workarounds? I am really not comfortable slipstreaming. I have a legit copy of XP Pro with a cd key and all that jazz. I have had previous success installing a different copy of XP Pro on my MBP.
