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

[Ty Young]

I've personally never used update-grub before, so unless the command was
given by an update, no.

I run Windows 7 and Ubuntu Gnome on separate hard drives. I had
unplugged the Windows 7 HDD for the boot-repair.

Don't think so since it happens when restarting from Ubuntu Gnome and
never from Windows 7 to Ubuntu Gnome if the option was there before
restarting Ubuntu Gnome.

If it matters any, I get a duplicate UEFI entry for Ubuntu, named after
the hard drive model(Model: ST3750528AS). If i select it, the screen
flashes blue and enters grub as normal(or looks normal, anyway).

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

Status in grub package in Ubuntu:
  New

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.
