Comment 17 for bug 1387654

Thanks for the above.

My process was to boot into live environment, then (as root):
- Set up my chroot as per http://superuser.com/questions/376470/how-to-reinstall-grub2-efi
- Add deb http://au.archive.ubuntu.com/ubuntu/ trusty main restricted to my /etc/apt/sources.list
- apt-get update
- apt-get install efibootmgr=0.5.4-7ubuntu1
- update-grub
- efibootmgr -c --disk /dev/sda --part 2
- efibootmgr -v # verify a new record called Linux is there

Reboot and happy days
Thanks everyone for your contributions
