This generally means that the version of grub being loaded from the
mbr + embedded area at boot does not match the version whose files are
in /boot/grub/.

Most likely you did not run grub-install to the device your BIOS is
actually booting from. Try running grub-install against all drives but
*no* partitions and be sure that you run "sudo dpkg-reconfigure
grub-pc" once you're booted into Ubuntu and select all drives there as
well. If you don't do the dpkg-reconfigure step then this problem will
return when the grub-pc package is upgraded and /boot/grub gets the
new modules without the correct mbr+embedded area also being upgraded.
