I screwed up: I have a MBP with 10.5 on it. A while back I installed XP with Boot Camp. I probably used Fat32 for the XP partition. Today I decided that I would remove XP and try out Windows 7 beta. I used Boot Camp to delete the XP partition. I then used Boot Camp to make a new partition and then I started the Windows 7 install. Windows stopped and said that it needed an NTFS formatted partition. I didn't see a way of doing that formatting within the windows installer, nor was there a way to change the Fat32 to NTFS with the options in Boot Camp, nor with the OS X Disk Utility. A friend of mine suggested doing the XP install which would allow me to select a format at the beginning of the XP install. A fine idea, UNFORTUNATELY I wasn't paying attention when I formatted the C: drive (instead of the other drive I had just partitioned) and that wiped out my OS X partition! The only fortunate thing is that I had at least backed up my wife's itunes earlier in the day and I don't have any important files that I lost on that machine. The problem now is that I can't load OS X from the install disk because the drive is formatted NTFS. The computer loads the install disk but can't proceed through the install. How should I proceed? If I put in the XP disk I think it will allow me to reformat to Fat32 but I'd rather do the formatting with some Apple utility that would format the disk like it comes from Apple.
