i had grub & RH9.worked fine until the mbr got overwritten by winxp! that should`nt be to hard to fix from recovery console,but my cdrom drive died some time after that!now the RH9 instalation "lies dorment" on it`s partition because i ca`nt reinstall grub on the MBR.i have a network conection trough LPT

,so i can use the other computer`s cdrom to get some small progrs.i also have all 3 iso files of the RH9 install cds on my hdd.how can i restore grub (or LILO or something else) on MBR so i can boot into RH9?
