It should have made it that far.  Even if it didn't you can repair /boot
from the live CD, or you can chroot the entire install from a liveCD and
repair it that way (the method we prefer to use here in house because we
can do a vast amount of integrity checks on a *dead* system as we
repair.  I mean real integrity checks, ones we would never do on a live
system.)

Anyways, if you send me a layout of how you do your partitions I can
send you a personal email with how exactly to do the CHROOT repair we
do, without that I would have to give you a general description which
might or might not help.
