okie the default fstab file i believe is going to be /hda1 for the boot. (I in fact did this with my gentoo system a while ago and am trying to remember what i did to fix it. so try setting it in your lilo, edit it so it points to the hda1. If that doesnt work setting single won't work so other then that erm...having a backup after this would be useful.
that's the only thing i can think of right now is setting it to be the same as the fstab folder.
