2.5 chroot into your / partition or alternatively tell grub-install 
where to find /boot(read the man page I don't have an i386 system near 
me at the moment)

Alternatively(again) you could type at the grub boot prompt:
root (hd0,2)
kernel /boot/vmlinuz-2.6.10-2 root=/dev/hda2
initrd /boot/initrd-2.6.10-2
boot

I'm not sure on what your kernel image or initrd image are going to be, 
but grub has tab completion.  Also I might be getting the root directive 
wrong.  grub has integrated help, so type "help" to get general help and 
"help root" to get help on the root directive.

Once you get into your system with either of the two above methods(I 
perfer the second) run grub-install /dev/hda again.  Remember, grub is 
very robust and if its at all installed on the system and you can get 
into grub, chances are you can get into whatever system is installed on 
that computer.
