On my HP dc5800 microtower I got same problem. Continuing on JohnL messages: Just downgrading grub also resulted in some 'hybrid' for me. Cleaning up a bit more brought me to the 'oldfashioned' grub. So far (a few reboots) no problem anymore. What I did:
sudo apt-get purge grub-pc sudo rm /boot/grub/* sudo apt-get install grub sudo update-grub sudo grub-install /dev/sda (replace sda with your boot device!)
