I booted using the Edgy Knot 1 CD and had the same problem. However I looked at the partition list and saw what was wrong: There is a zero length partition (partition 7) that overlaps with another partition (number 6). I deleted partition 7 and it solved the problem.
It looks like parted needs better error recovery, so that it can be used to solve this kind of problem. I had to use fdisk. -- Parted fails to correctly read partition table https://launchpad.net/bugs/55731 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
