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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1466150 Title: grub-install breaks when ESP is on raid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1466150/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
