[Bug 1066325] Re: Failing to install boot loader - 12.10 daily build October 12

[melchiaros]

With the line you can find above and following

Oct 14 13:34:15 ubuntu grub-installer: error: Running 'grub-install
--force "/dev/sda"' failed.

it is a problem with grub-installer.

I will attach also this package here and keep the report open for grub2
and ubiquity, because I could not decide which causes the error.

** Also affects: ubiquity
   Importance: Undecided
       Status: New

** Project changed: ubiquity => grub-installer (Ubuntu)

** Changed in: grub-installer (Ubuntu)
       Status: New => Confirmed

  Failing to install boot loader - 12.10 daily build October 12

Bug description:
  Having run 12.10 beta 2 in a KVM I decided to install the latest daily
  build for real only to encounter a fatal error during installation.

  The install seems to run fine until suddenly reporting: Executing
  'grub-install /dev/sda' failed. This is a fatal error.

  I have 2 drives - /dev/sda is a 3TB hard disk, and /dev/sdb is a 128GB
  SSD. I was installing onto /dev/sdb so got a bit freaked out that it
  was trying to install a boot loader to /dev/sda.

  Manually telling the installer to use /dev/sdb instead did not work
  either, so have a system without boot loader.

  Am currently downloading beta 2 again to attempt an install with that
  image (to determine if it's something that's gone wrong since beta 2
  or whether it's a hardware compatibility issue). Previous OS on the
  SSD was 12.04, but I chose a complete re-install replacing the OS
  rather than an upgrade.

  1) cat /proc/version_signature > version.log : Ubuntu 3.5.0-17.28-generic 3.5.5
  2) sudo lspci -vnvn > lspci-vnvn.log
