I think I know what you need to do: once you've got the /boot restored,
and the LVM mounted (the liveCD ought to let you do that), then you need
to chroot to the mounted fixed drives, and
grub-install /dev/sda
(or whatever it is). Then you may want to edit /boot/grub/device.map to
only show (hd0,0). And DON'T FORGET to create /boot/grub/grub.conf!
That should do it.
