Title:
  GRUB writes to wrong MBR and destroys RAID setup

Status in grub package in Ubuntu:
  Invalid

Bug description:
  With the Feisty Final Desktop 7.04 LiveCD, the installer detected my
  40gb primary hard disk as "SCSI0" and my hardware RAID drives as hda1
  and hda2.  I boot Windows XP from the Primary 40gb hard disk (SCSI0)
  and I created Ubuntu's partitions in a second primary partition on
  that physical hard disk.

  Ubuntu installed to this partition without a hitch, but no options
  were provided for the installation of GRUB.  GRUB automatically
  overwrote the MBR on the WRONG HARD DRIVE which was a member of my
  hardware RAID-0 array, thus breaking the array.  I did NOT intend for
  the OS to make any changes whatsoever to these two physical disks as I
  had not even attempted to configure any raid drivers yet.  However,
  since the array disks were detected as hda1 and hda2 I guess GRUB
  assumed that those were the primary boot hard drives and thus wrote
  the MBR to hda1 instead of the *actual* boot hard drive SCSI0.
  Fortunately, the data was recoverable.

  The installer should provide options of whether or not to install
  GRUB, and also WHERE to install GRUB.
