[Bug 1561842] Re: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.

[Erick Brunzell]

Based on what's said in comment #3 I suspect that there is an EFI System
Partition on both the Windows drive (which was disconnected when boot
info was gathered) and the Ubuntu drive. That becomes problematic and
really is just a limitation of UEFI in itself. I still frequently run
into problems with UEFI that require I ask a question at Ubuntu Forums
and wait for oldfred to get me straightened out.

Title:
  Grub bootloader disappears after a seemingly random amount of
  restarts/shutdowns.

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  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.
