Comment 133 for bug 1289977

@olly_b, the dpkg-reconfigure grub-pc only applies if you are booting in bios mode.

@Saurabh, the question was *what* output, not whether or not it exists. Also what is the output of sudo efibootmgr -v?

@Terry, once again, running grub-install /dev/sda fixes it today, but breaks the next time grub is upgraded. You need to use dpkg-reconfigure grub-pc so the system remembers that it needs to run grub-install /dev/sda after the next upgrade. Also, once again, it can't be validated in an automatic way.
