installing GRUB
i re-install with my FC3 , i think it will be the same with RH
1- boot using CD1 of FC3.
2- dont enter graphical mode but instead enter the following command linux rescue
3-enter the following : chroot /mnt/sysimage
4-enter the following : grub-install /dev/hda --note i assumed that ur disk which u want to boot 4m is hda , u should change it according to ur disk "can be hdc in case of two disks , i think hdb is for the CDROM"
5- enter : exit >>>or just restart
