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

[Erick Brunzell]

Just checking my email this AM and reading your recent replies to Ubuntu
GNOME mailing list i see you included a boot info summary with both the
Windows drive and the Ubuntu drive connected:

The output of parted -l shows Win 7 is installed non-EFI but Ubuntu is
installed in UEFI mode:

=================== parted -l:

That is, in itself, problematic. So please open a new thread at Ubuntu
Forums here:

http://ubuntuforums.org/forumdisplay.php?f=333

One of the forum mods there uses the moniker oldfred and he'll be able
to answer your question and help you get that straightened out. My
method would be to back up all the data on the Ubuntu drive and
reinstall in non-EFI mode after creating a new msdos partition table on
the Ubuntu drive, but there may be a simpler way :^)

Please do be patient and wait for oldfred to reply.

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.
