I'm not sure this is a duplicate. In bug 8497, the reported problems all involved multiple hard disk systems where the wrong hard disk number was assigned in menu.lst. In this case there was only one hard disk and the hard disk number (hd0) was always correct. The problem that occurred was with the partition number on the hard disk, i.e. (hd0,4) when (hd0,5) was what worked.
