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

[Phillip Susi]

The  boot code does not know or care about sda vs sdb, so that isn't it.
It appears to have installed grub just fine for bios mode, so if you
aren't at least getting a grub error or rescue shell or menu, it must be
a bios configuration problem: make sure your bios is configured to boot
from the hard drive in bios mode.

You also might try using fdisk to set the boot flag on the GPT
protective partition; some very stupid bioses refuse to boot if they
don't see a boot flag set.  Or, just stick with the full uefi mode
install if that works for you.

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.
