Title:
  Windows Vista won't load from grub2

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub2

  I recently switched from Wubi Ubuntu to a dedicated partition for Lynx
  10.04 LTS.  I am now unable to boot to Windows Vista (which I have to
  do because of some programs Yuk!).  When I choose Vista, the computer
  simply reboots.  I have found that this is because Grub detects Vista
  at hd 0,1.  If I edit the command line manually each time I choose
  Vista so that it points to hd 0,0, Vista boots fine.  The hd 0,2 is
  the recovery drive for Vista, and also reboots the computer.  How do I
  get the hd designation of 0,0 instead of 0,1 to stay in the grub.cfg
  so that I do not have to edit it every time?  I did try to find this
  issue before I opened this bug, but I wasn't able to find this one.  I
  do see other issues that are similar, yet they are not the same.  I am
  still a relatively new Ubuntu user, and would appreciate any help you
  can me.  I am concerned that if other newbies are having this issue,
  they will think that Windows is gone, when in fact it is still there
  and perfectly intact.  Thank you.

  grub-install (GNU GRUB 1.98-1ubuntu6)

  sudo os-prober
  /dev/sda1:Windows Vista (loader):Windows:chain
  /dev/sda2:Windows Vista (loader):Windows1:chain

  ### BEGIN /etc/grub.d/30_os-prober ###

  menuentry "Windows Vista (loader) (on /dev/sda1)" {

          insmod ntfs

          set root='(hd0,1)'

          search --no-floppy --fs-uuid --set 3552fd5b77ee05b4

          chainloader +1

  }

  menuentry "Windows Vista (loader) (on /dev/sda2)" {

          insmod ntfs

          set root='(hd0,2)'

          search --no-floppy --fs-uuid --set 7224f19224f15995

          chainloader +1

  }

  ### END /etc/grub.d/30_os-prober ###
