Right, you have two disks on this system and you're only installing GRUB
to the second one.  There's probably a vestige of GRUB on the other disk
which happened to be compatible with the modules from 2.00-22 but not
the modules from the new version.  I recommend running:

  sudo dpkg-reconfigure grub-pc

Step through without changing anything until you get to the "GRUB
install devices:" question, and then select the master boot records of
both your hard disks, rather than just one of them.  That should fix it.
