Title:
  Grub - Error 21 returned

Status in “grub” package in Ubuntu:
  Invalid

Bug description:
  Hello,

  After installing Ubuntu on a clean disk, GRUB returns the following error on
  startup :
  "
  Grub Loading stage 1.5.
  Error 21
  "
  Error 21 means :
  "
  21 : Selected disk does not exist
      This error is returned if the device part of a device- or full file name
  refers to a disk or BIOS device that is not present or not recognized by the
  BIOS in the system.
  "

  My motherboard is a ABIT KR7A-RAID with a Highpoint hpt372 controller for RAID
  (This motherboard has two normal IDE and two IDE for RAID).
  This error is returned when my HDD in plugged on a "RAID" IDE. (By the way, I
  don't use RAID, it's a single disk).
  Ubuntu installation works if I plug my HDD on a normal IDE.

  I encounter no problem when I install Fedora Core 2 with my HDD plugged on a
  "RAID" IDE (and with GRUB) (so I don't think it's a BIOS problem).

  Thanks
