It is very strange that grub (which was already installed and working)
would go bad during an upgrade.
I would boot from a CentOS-4.3 CD-1 and do this command at the isolinux
If it mounts the install at /mnt/sysimage ... do this:
Then I would follow this guide to make sure that grub is installed on

(comment #7 should make you work ... assuming you have a software mirror
using sda/sdb or hda/hdb)
You may need to look at the file /boot/grub/Device.map to insure all the
