[Bug 1054815] Re: grub installer for 12.04.1 system installer is easily confused

I'm sorry, I don't think I will be able to break my now-working system
to get log files.

Title:
  grub installer for 12.04.1 system installer is easily confused

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  When installing 12.04.1(using the third install option that brings up
  the partition too) I merged two partitions on a non-removeable
  /dev/sdb, the result becoming mount point /.  At least one of the
  original partitions contained an old ubuntu installation, maybe both
  did.  The existing grub installation may have been on one of those
  partitions or grub may have been associated with yet another partition
  that was capable of booting into one or both of the old ubuntus (I
  don't remember which way it was).  So in some way the existing grub
  would have been at least partially broken by the merging of the
  partitions.  I figured "what the heck" the install can easily figure
  all this out and install a working grub.  No it can't.  With repeated
  installs of 12.04.1 I'd either get "grub rescure>" or sometimes a
  partition UID not found error (one of the now-gone partitions' UID
  names).  Each time, a Boot-Repair CD from sourceforge restored grub to
  working condition with three button clicks.  Note: one of those clicks
  asked if /dev/sdb was a removeable disk.  Ubuntu never asked that.  I
  wonder if Boot-Repair uses that info to correctly handle some
  condition that maybe ubuntu doesn't.  In any case, the ubuntu
  installer gets terminally confused where Boot-Repair works fine.
  Seems like looking into Boot-Repair is a good place to start in
  improving the installer.
