Comment 10 for bug 1466150

I agree that the severity is incorrect. Whenever grub-install is run - ie when the version of grub is upgraded - I end up with an unbootable system. Yes, my trusty rescue disk sorts it out but that's not a solution.

Referring to the comment above, I have two EFI entries, one for each disk. They both get trashed by grub-install so I recreate them by hand - either before reboot or after using the rescue disk.
