Yeah, and I have some custom stuff for other reasons, multiple partitions, multiple systems... And then automated updates mess it up.
For anyone following this critical story, here are the commands to recover:
set boot=(hd0,gp5)
set prefix=(hd0,gp5)/boot/grub
insmod normal
normal
and then when you boot
sudo update-grub
