Title:
  Grub: menu.lst wrong

Status in grub package in Ubuntu:
  Invalid

Bug description:
  I have a new Toshiba Satellite laptop on which I had installed FreeDOS
  in the other primary partition (Toshiba's recovery partition) besides
  the one Vista occupies.  Then I installed Ubuntu 9.04 (in its own
  logical partitions).  The menu.lst that was set up automatically
  correctly recognizes the other 2 bootable OSs.  However, it does not
  work correctly.  The symptom when trying to boot Vista was the error,
  "autochk program not found - skipping AUTOCHECK", which occurs early
  (but not immediately) during the bootup.  Initially, FreeDOS would
  boot.  (It was the active partition when I installed Ubuntu.)  I got
  Vista going again by booting up GParted from a live CD.  I correctly
  set the active and hidden properties for the Vista partition, after
  which Vista would boot but then FreeDOS would no longer boot
  correctly.

  I was able to fix the problem by adding, in menu.lst, a pair of
  hide/unhide commands for each of the relevant partitions.  E.g., for
  FreeDOS on (hd0,3):

  ...
  hide (hd0,1)
  unhide (hd0,3)
  makeactive
  ...

  It appears that a hidden partition will not boot properly.  I do not
  know why grub-update does not insert the hide/unhide commands; but it
  appears that something along these lines is required.  I do not know
  of anything particularly unusual about my situation that would have
  caused this failure.  (I am no expert on Grub, but I did read some of
  the FSF's documentation for it to learn about partition names and the
  hide/unhide commands.)
