[Bug 1308758] Re: Ubuntu 14.04 install blocks Windows 8.1 from booting in dual boot

[Mathieu Trudel-Lapierre]

Hi Don,

So I can make sure I understand properly, when you hit F12 you can
select Windows or Ubuntu and they both boot properly when selected, and
on top of that, when you select Ubuntu you get the Grub menu and can
choose between Ubuntu and Windows there as well?

I'm trying to confirm that the only problem at this point is that you
need to hit F12 to get to Ubuntu; otherwise the computer boots straight
to Windows?

Furthermore, what make and model of system is this? Could there be a
BIOS firmware update available that would allow enabling boot order
selection? Does boot priority currently only give you a choice between
"UEFI first" and "BIOS first"?

Finally, try to run 'efibootmgr' from Ubuntu and include its output here
on the bug.

Thanks!

Title:
  Ubuntu 14.04 install blocks Windows 8.1 from booting in dual boot

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  My computer is 5 months old. Was dual booting Windows 8.1 and Ubuntu
  13.10. No issues. Did a clean install of 14.04 final beta to the
  partition which had 13.10. Upon restart, I can only boot to Ubuntu. If
  I try windows from grub menu, it reverts right back to Ubuntu. If I
  try windows from a bios selection before loading grub, as soon as I
  select windows, grub appears, and will only load Ubuntu. Ubuntu is
  installed in efi mode. Ubuntu and windows both are in the efi
  partition. I ran the boot-utility for saucy since I didn't find one
  for 14.10. It did not fix the problem. As of now, I'm locked out of
  Windows 8.1. Another person had the exactly the same thing happen both
  on the first install with 13.10 where Ubuntu would not boot, and now
  on the upgrade to 14.04 where windows 8.1 will not boot. See
  http://askubuntu.com/questions/447568/windows-8-entry-in-grub-not-
  working

  Version: Description:	Ubuntu Trusty Tahr (development branch)
  Release:	14.04

  Grub 2.02~beta2-8 -  All check boxes in synaptic for grub are grayed
  with an ! point in.
