finally, im posting this message in Linux!
to answer your question:
i was putting the MBR onto hda
i had another search through google, and found someone else with the EXACT same problem, and he told me to boot with the Fedora CD, and go into the linux rescue part and type the following:
chroot /mnt/sysimage
grub-install --recheck dev/hda
reboot
upon reboot up came GRUB and here i am!
thanks a lot for all your help sam
(and btw, i quite like linux so far, just gotta try and find a better MSN Messenger, don't like that crappy GAIM)
