Your Answer

This problem happens because the Snow Leopard installer detects a small discrepancy in the partition table of the drive, and assumes booting off the drive may not be successful. The fixes involve rewriting the table without formatting the drive, but if that does not work then formatting should definitely work provided you have a backup.

The first thing to do is run Disk Utility or, even better, run a third-party utility program to check out the drive to ensure it is functioning correctly. Fixing any errors may require booting off a volume other than the boot volume i. This problem might happen even if the drive checks out with various disk utility software. The way around this is to have Disk Utility repartition the drive, which, luckily, can be done without having to format the drive. Then launch "Disk Utility" from the "Utilities" menu and perform the following steps:.

After this is done, quit out of Disk Utility and try installing Snow Leopard again. Since you are booted from the Snow Leopard DVD you should be able to continue immediately without having to reboot your system. If you have a full system backup via Time Machine or a drive clone, you can format your boot drive and do a clean install of OS X.
