When booting with a rescue CD, are you first mounting the root (/)
partition at a {mount point} in the Live CD environment, and then
mounting the /boot partition under {mount point}/boot?  That way the
boot partition is mounted at the appropriate place in the tree
structure.  Then chroot to that mount point so that it becomes your
root.  Then a /sbin/grub-install?  Otherwise if you don't mount your
partitions starting at / and then mounting the others below it at the
appropriate place in the tree structure and then chroot it will not
work.

Having said all that I am not 100% clear if you said some of your
partitions won't mount.  If that is the case, then the issue is
probably not with grub so a re-install will not likely correct your
problem.
