Title:
  grub2 fails to boot windows correctly

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub2

  After installing Ubuntu 9.10 beta, windows fails to boot.  On
  selecting windows on the grub boot menu, I get an error similar to:

  "Windows could not start because the following file is missing or corrupt:
  ...\system32\ntoskrnl.exe"

  I can boot windows fine using the "Super Grub Disk" boot CD from
  http://www.supergrubdisk.org/, so it seems like it's not a problem
  with windows. This is the automatically generated entry in grub.cfg:

  menuentry "Microsoft Windows XP Professional (on /dev/sda1)" {
          insmod ntfs
          set root=(hd0,1)
          search --no-floppy --fs-uuid --set 6e2cf50d2cf4d0d7
          drivemap -s (hd0) ${root}
          chainloader +1
  }

  Partition info from parted:
  Model: ATA ST3200820AS (scsi)
  Disk /dev/sda: 200GB
  Sector size (logical/physical): 512B/512B
  Partition Table: msdos
