Have you found a fix to this yet? I have the same problem. I have a Hard drive with windows and Hardy dual booting. I went to upgrade to Intrepid and then upon reboot I had that same error message. I can't access anything unless i'm on an old Hardy live cd. I've searched the forums and no luck yet. here is what comes up when i hit fdisk
