I think I may have found a bug in the version of Grub that comes with RH8. I had previously tried everything mentioned here on an upgraded RH71 -> RH8 machine, with the same results: "GRUB Read Error" being all I'm getting when I boot. So I grabbed a test box, installed RH71 on it, and then upgraded it to RH8. THEN, I yanked the grub RPM from the RH73 install CD, installed it, and created /boot/grub/grub.conf. Then I ran lilo -u grub-install /dev/hda grub and in the grub shell I ran root (hd0,0) setup (hd0) When I rebooted, everything worked great! Then as a test, I installed the RH8 grub RPM and rebooted. Still worked, but the version number was wrong, so I got into the grub shell and re-ran the setup commands above. Rebooted... "GRUB Read Error". I guess the next step is to report it as a bug?
