The problem occurred when I tried to upgrade my system from RH 6.0 to RH 6.1. The installation program could not mount the ext2 partition and aborted. It probably got confused because I have 6 partition and only one IDE hard drive. The partitions are hda1 - DOS hda2 - NTFS hda3 - extended partition hda4 - ext2 hda5, hda6 - Linux swap If you need more details please e-mail me.
