Well, that output from fdisk shows you have an empty partition table. This doesn't explain how grub can load and even load a configuration - do you have your boot partition on a separate disk? If not, I'm inclined to guess a driver problem. You might try these instructions using a Knoppix disk (or similar) http://ftp.ibiblio.org/pub/linux/docs/HOWTO/other-formats/html_single/Partition-Rescue.html -- You received this message because you are subscribed to the Linux Users Group.
