[Bug 1286047] Re: Ubuntu 13.10 not booting on hardware RAID

[Hag K]

Please see attached PDF which contains screenshots and further
explainations. I know the PDF turned out quite large due to the mobile
phone fotos but I believe it should clarify what's going on.

As of the information provided with the attached PDF, I think that the
problem is introduced once Ubuntu 13.10 is installed by using an USB
Stick without the UEFI option. This way the boot record ends up pointing
to "sdb" rather "sda" since the installer orders the USB Drive as "sda"
and the RAID disk as "sdb". However after the installation has finished
and the USB Stick is removed, there is not "sdb" drive and thus no
bootable device is found and the UEFI/ BIOS user interface shows up
instead.

Title:
  Ubuntu 13.10 not booting on hardware RAID

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  Steps to reproduce with Ubuntu 13.10:

  1. Setup the adaptec RAID controller to use ANY of the RAID modes
  2. Install Ubuntu 13.10 (in my case from USB) by using either classic partitioning or LVM
  -> Observe that the installer correctly finds the RAID disk and the installation process finishes successfully
  3. Boot the system
  -> Bug: System does not boot into the newly installed Ubuntu 13.10

  Hardware:
  - ASUS H87I-PLUS Motherboard with latest UEFI/BIOS update
  - Adaptec RAID 6405 Controller

  Note the issue reported here is not encountered with Ubuntu 14.04
  daily build (downloaded 27/02/2014). So it appears that Grub 2.02 used
  with Ubuntu 14.04 has a positive impact as it resolves the bug. I hope
  this will be another good reason to ship Grub 2.02 with Ubuntu 14.04
  LTS.
