Don't Be Put Off By this Big Wall of Text if you know anything about Boot Camp and Disk Utility Please Help. Ok this story starts a while back, I want to get Windows Vista Business on my MacBook so I tried to partition my disk it didn't work I read the Boot Camp guide and Backed Up and Erased my Hard Disk on Disk Utility and restored it and the Partition worked that time. But when I installed my Windows Vista I needed a different serial number so I gave up on that and decided to delete the Windows partition, what I found out is that the Windows Vista automatically deleted my Mac OS X partition. Heres where I think somehow I went wrong using Install Disk 1 and Disk Utility I deleted the Windows FAT partition and using the partition tab in Disk Utility I made a new Macintosh HD partition. So a week down the line I've acquired a Windows XP SP2 disk from a friend and wanted to make a partition for the Windows but when I open Boot Camp Assistant and press continue it reads "The startup disk cannot be partitioned or restored to a single partition." I've tried erasing the Disk and restoring the Disk using Time Machine a few times and Boot Camp still reads"The startup disk cannot be partitioned or restored to a single partition." Its infuriating. And I've searched all the forums but this is too specific and so I've signed up here to ask anyone who could help. Anybody got answers?
