Public bug reported: This happens on Ubuntu-Gnome 14.04.X(X being initial release and all point released after) through 15.10. The OS itself is fine and can be booted into again by reinstalling Grub but will eventually happen again.
This bug can happen right after a new install of Ubuntu-Gnome or many months after. When it does happen, the system works and acts the same as before and after the bug.
