Hi
This is a sample config:
root (hd0,2) // Partition 0 and partition 2 on the harddrive
install --stage2=/boot/grub/stage2 /boot/grub/stage1 (hd0) /boot/grub/stage2 0x8
000 (hd0,2)/boot/grub/menu.lst
quit
Grub is not like lilo. Grub is automatically updating itself if there are any changes and lilo is not. You could start the installation again though without deleting anything and then select reapair or some option like that and fix the boot loader. I have done this before so it is an option there which i easily accessible. You could also edit the /etc/grub.conf file or check it to see if there is something wrong there.
