When did you re-install GRUB (grub-insall)?
And when you did, did you have it use the _new_ grub.conf?

Consider booting the CentOS CD #1 in "rescue" mode.
Let it find your root and then chroot and run grub-install.

It's best to treat the two sets of discs/volumes as
different, and never put them in the same system. Again, use
CD #1 to boot into "rescue" mode, chroot and run grub-install
with only the new discs/volumes connected.
