[Bug 1775743] Re: [regression] Cosmic daily images 20180606-11 install but boot only to grub prompt on EFI systems

[Fred Palmer]

Just saw one thread in Ubuntu Forums & one in AskUbuntu where with 18.04
the Boot-Repair output from efibootmgr -v shows no ubuntu entry and only
has a grub entry.

See:
https://ubuntuforums.org/showthread.php?t=2396042
And:
https://askubuntu.com/questions/1053895/system-always-boots-to-grub-prompt?noredirect=1#comment1722812_1053895
This user already reported that copying /EFI/grub/grub.cfg to /EFI/ubuntu/grub.cfg fixed his boot issue.
