[Bug 1201257] Re: Ubuntu doesn't boot from Windows 8 boot menu

[Steve Langasek]

Thanks, this is very interesting; it shows that not only does your
firmware include the expected Microsoft key, your firmware *also*
includes the Canonical Secure Boot key.  This makes it doubly surprising
that the stock Ubuntu image doesn't boot under Secure Boot.  Did you add
any of these keys yourself, or did these come by default in your
firmware?

How did you prepare the Ubuntu USB disk?  The preferred way to do this
is with a direct dd of the ISO onto the USB disk; the ISO is a hybrid
image which is bootable out of the box as a USB disk, whereas many USB
"image creator" programs try to modify the image in unpredictable ways
when writing.

Yes.  I've focused on the Secure Boot problem, because I understood that
to be your priority.  The other problem with booting under the Windows
bootloader is probably not one that we will commit to fixing.

Title:
  Ubuntu doesn't boot from Windows 8 boot menu

Status in “shim” package in Ubuntu:
  Incomplete

Bug description:
  Here are the information and the exact steps I followed:

  - My laptop is ASUS S56CB with Windows 8 pre-installed.
  - Prepared partitions using Windows' own disk management utility.
  - I prepared a Ubuntu 13.04 (64 bit) ISO to boot with a USB.
  - Disabled Fast Boot. When I tried to install Ubuntu in UEFI mode, Secure Boot didn't allow, then I also disabled Secure Boot.
  - Everything went fine and installation started. I continued in the normal way till the partition point.
  - I created an EFI partition, "swap", "root" and "home" partitions and set the bootloader to be installed on the EFI partition. I don't want to use Ubuntu's GRUB loader, so I didn't install GRUB on dev/sda, but on dev/sda5 as the Ubuntu EFI partition was there.
  - Installation finished, and I opened Windows 8. Using EasyBCD, I created a new boot entry and rebooted to see if it would load Ubuntu.
  - When I choose Ubuntu entry, I get this error:

  File :\NST\AutoNeoGrub0.mbr
  Status: 0xc000007b

  If I try starting Ubuntu from UEFI (by pressing Esc while the computer
  boots), I'm able to boot into Ubuntu. However, as I stated it doesn't
  work in Windows 8's boot menu.

  The problem related to Windows 8's boot menu not starting is another
  issue, but the real problem is that Ubuntu cannot be installed in this
  computer without disabling Secure Boot.
