I gave that a try but it did a verify and said everything is fine with the hard drive. I read up some elsewhere and it seems the problem is I need a GUID partition table. I think why I'm running into this problem is I bought this MBP about a year ago with a 160GB hard drive. About 4 months ago I upgraded it to a 250 GB hard drive by mirroring my 160 using SuperDuper. I read elsewhere that this could be the problem and the best way to do this is reformat my drive as GUID and then set up Leopardl. I've done a complete format with Disk Utility though and it's still giving the same error msg. Any other ideas of what I can do?
