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

@Phillip Susi

No,  I'm not able to find a particular cause for it. As I had said, the
system works and acts perfectly normal before this happens and works
normal after installing grub again.

I'm a bit confused as to how the motherboard/BIOS could have just
*forgot* that Grub existed. Not that I'm calling you a liar or anything,
its just I've had Windows 10 Insider Preview(UEFI install) and
SteamOS(for a short period of time, anyway) as well as Windows 7 that
came with my computer installed  had/has no such issues.

@Erick I'm very certain the Windows 7 HDD isn't UEFI as I've never seen
any indication that it was.

If it matters any, I have two Ubuntu boot options for Ubuntu Gnome:

1: ubuntu

2: UEFI: ST3750528AS (hard drive model)

Booting into the UEFI option causes the screen to flash blue and text to
appear for not even a second before showing the GRUB bootloader. I don't
know what it says as it flashes so fast. Booting into the "ubuntu"
option just takes me straight to GRUB menu.

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.
