This bug should have a very high priority. It is a known bug in GRUB and it is already fixed upstream: http://savannah.gnu.org/bugs/?35382
This bug prevents (U)EFI systems from booting. If you know grub really well, and your partition layout really well, you can manually specify all the parameters and commands necessary to boot at the rescue prompt starting with the "prefix" which is probably set to the wrong drive. Please package the upstream fix for ubuntu before this disasterous bug gets into the wild! ** Bug watch added: GNU Savannah Bug Tracker #35382 http://savannah.gnu.org/bugs/?35382 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/975061 Title: grub doesn't find boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/975061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
