Here's the deal... I had XP on a partition that I could either Boot Camp into or pull up via Parallels. I removed the partition with Boot Camp Assistant. I then used Boot Camp Assistant to make a new, smaller partition to reinstall Windows XP to. Everything was going fine during XP install until it went to reboot, but came back with "disc error. Press any key to reboot." (I pressed keys, but nothing would happen. I had to power down and back on.) Now all I can get is that error message. If I hold the Option key and bring up the boot menu to boot into Windows partition, it gives that error message. I'm back into OS X now, and see the "BOOTCAMP" icon on my desktop... I run Boot Camp Assistant again, gonna try to just remove the new partition and start over... But when I try to go through Boot Camp Assistant, it says, "The startup disk cannot be partitioned or restored to a single partition. Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again." What am I supposed to do? I just wanted to downsize the XP partition from 60GB to 30GB... Someone please offer some help It will be greatly appreciated.
