o, u have lilo installed, my bad....
then maybe u can change.... (though i strongly recommend u don't if u ever intend to try other distros which is highly likely, lilo is much more universal and more widely used, u can also do some cool things under lilo, especially if u install slackware's lilo)
ya, lilo is kind of ugly when u see it, that's y i stood away from it a lot but i regretted that once i starting installing other distros; only redhat seems to like grub
anyway, trying going into a terminal, type "su -" then the password for root when prompted, and they type grub-install /dev/hda or /sbin/grub-install /dev/hda and see what happens
(and if you're talking about the little graphic that comes up in grub's screen, i think u can do that in lilo too, i'll see if i can did that up)
