I'm having issues setting up a Tri-boot system on my Macbook. I can't figure it out at all. I've created the partitions, and began installing XP. After the set up, the machine reboots to finish the install, but I get a 'disk error: press any key to reboot' error after the install. I am not installing though Bootcamp, and I have insured the drive is an NTFS drive, as that is reason the disk error usually appears. am I missing something simple?
