Can you use the redhat 9 cd to boot into your Linux install, and try to reinstall GRUB from there?

yes I can

Well, then I suggest you do that . It's easier to install GRUB from within Linux then from a floppy or CD.

if u are reinstalling the grub it will not work. here we have two stage of boot loader. the satge 1 is there in ur MBR stage 2 is there in ur /boot directory or partition.. u are getting grub command prompt y because ur second stage loader is missing. do the following commands. u have windows also right?. so i hope windows is installed on c drive? if it is like this do the following
grub> rootnoverify (hd0,0)
grub> chainloader + 1
grub> boot
these three steps for booting to windows. do the following for linux. i hope ur linux boot partiton on /dev/hda2
grub> root (hd0,1)
grub> setup (hd0,1)
grub> kernel /vmlinuz-2.4.21-4 ro root=LABEL-/
grub> initrd /initrd-2.4.21-4.img
grub> boot
if ur boot partition is there then this will work.
