[Bug 1229886] Re: Grub2 cannot bring Win 7 out of hibernation - error 0xc000009a

[S Silverstein]

Re:  João Henriques (joaoh88)  - I'm having the same problem, cannot
resume Windows from grub, but going into settings and overriding the
boot sequence and choosing windows bootloader allows hibernation to
resume state.

I can override the BIOS boot sequence to bypass Grub,  but when I select
the Windows bootloader I get a black screen with the text message "No
boot disk detected or boot disk has failed."

Did Grub inastallation possibly rename the windows bootloader?

Note the entry in my /boot/grub/grub.cfg file as posted earlier:

menuentry "Windows Boot UEFI loader" {
search --fs-uuid --no-floppy --set=root 96AD-5B21
chainloader (${root})/EFI/Boot/bkpbootx64.efi

Title:
  Grub2 cannot bring Win 7 out of hibernation - error 0xc000009a

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  Installed Ubuntu 12.04  for dual-boot on HP P7-1222 (a UEFI machine
  that came with Win 7).  All Ubuntu and Win 7 updates are installed,
  current as of 9/20/2013.

  Ubuntu works well. The 'Grub2 "Windows Boot UEFI loader" selection
  boots Windows 7 64-bit fine, too.

  Problem is: Win 7 cannot resume from hibernate.

  Pre-Ubuntu I had activated Win 7 hibernation and used it successfully.
  I like to hibernate my Windows machines and then unplug them to
  protect against voltage spikes etc., but have a fast restart with
  retained state.

  After Ubuntu was installed, if I hibernate Win 7 (which it seems to
  do) and the machine turns off.  If I then try to resume Win 7 from
  hibernation, I get a "Your computer cannot come out of hibernation
  0xc000009a" error from the Windows loader.

  If I try to reboot Win 7 again from Grub2 I am presented with the
  "delete hibernation file and restart" option, which then does so and
  reboots Win 7 OK. Of course, searching on the 0xc000009a error code
  brings up little of value. (Thanks, MS, for such informative error
  messages.)

  I've tried the "off the top of my head" attempted fixes - powercfg -h
  off, then powercfg -h on; defragmenting; etc. No change.

  In effect, I cannot use hibernation in Win 7 anymore.

  This seems to be a grub2 bug.  It does not occur on a dual-boot non-
  UEFI Celeron 352 machine w/Ubuntu 12.04 and Win 7 (note that the old
  machine is unning the 32 bit version of Win 7 but the 64-bit version
  of Ubuntu).

  I believe this is a Grub bug, but have no idea what source package the
  bug is in.
