Any thoughts on a workaround or next best steps? Anything dealing with grub always scares me because it impacts rebooting.

I have two instances running with the same provider (Linode). One upgraded fine about a month ago. The other has this grub-pc error. The only differences I noted in the /boot/grub folder was that the one that is not working has the default and menu.lst files present. Not sure if it is related but it would appear (anecdotally) that something changed between my upgrading of the two instances.
