Neither of these reasons (replies from Gunchev and Beever) were the reasons. The bios is set correctly, and grub is found. It sits for a minute dieplaying GRUB Then a minute or so later it says Loading stage2 Then very slowly 3 dots appear. Then a further minute or 2 later, the screen goes blank, and finally, a minute or 2 after that, the grub screen appears. After this, things boot fine... (Windoze or fedora) I think its also not a problem with the devices - Primary IDE master is a harddrive (master) and the other harddrive on this cable is set to slave. The secondary IDE cable just has a CD drive (master). Fedora is installed on the secondary harddrive. Any more ideas? Thanks.
