I attempted to install Boot Camp and it messed up my partition table to the point where there are no bootable volumes on my iMac except the superdrive. I think I made a mistake when I installed boot camp, I had an external hard drive plugged in at the time, and didn't think to unplug it, but I never selected that drive anywhere, I just read on another forum that sometimes having an external drive plugged in can confuse Boot Camp and Windows XP when you're installing it. I partitioned my internal hard drive using the Boot Camp Assistant and clicked on the default "use 32 gig windows partition option" It appeared to successfully repartition and then reboot to XP Pro install, but that's when everything went south. XP installed, but when it rebooted, it just booted back on the XP disc and tried to go back through install all over again. When I boot from the Leopard install DVD, it says "there are no available volumes to install Leopard to". When I open up Disk Utility, it shows my hard drive, but the volumes are not showing. It won't let me create any partitions or do anything with the disk, so I'm assuming the partitions are still there, perhaps the partition table is corrupted. Unfortunately, the disk first aid does not do anything, all options are greyed out in Disk First Aid, so I can't repair it with that. What other steps can I take to try and fix this issue? Are there some good 3rd party tools out there that can try to fix or rebuild a corrupted partition table? I really need help guys, please!! I can't even use my Mac, I'm writing this from my GOD AWFUL PC!!!!
