Title:
  [Karmic Alpha 5] update-grub gets confused when a second hard drive is
  plug before running it

Status in “grub2” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: grub2

  Karmic Alpha 5 live CD install, with only one HD (WD 640Go, SATA)
  connected on motherboard SATA1 port, Slave. The install doesn't pick
  up other OSes (see Bug #425379) though.

  After install, I plug a second HD (Samsung 1To, SATA) on motherboard
  SATA0 port, Master. The HD with Karmic moves from /dev/sda to
  /dev/sdb, the Samsung becomes /dev/sda.

  Running update-grub now picks up the other OSes, but throws these errors:
  > Generating grub.cfg ...
  > Found linux image: /boot/vmlinuz-2.6.31-9-generic
  > Found initrd image: /boot/initrd.img-2.6.31-9-generic

  /boot/grub/device.map has:
  (hd0)	/dev/sda

  grub.cfg after running update-grub is attached to the bug report, the
  original configuration at install can be found on Bug #425379

  Problem: only Karmic on /dev/sdb5 (WD) and Windows 7 Beta (reported as Windows Vista) on /dev/sda2 (Samsung) can boot. For booting Jaunty, grub2 reports this error:
  Error - you need to load the kernel first.

  Booting XP doesn't work either.
