Title:
  cannot boot windows after update-grub

Status in grub2 package in Ubuntu:
  Expired

Bug description:
  Binary package hint: grub2

  after running update-grub the windows entry looks like  this

  ### BEGIN /etc/grub.d/30_os-prober ###
  menuentry "Windows 7 (loader) (on /dev/sde1)" {
  	chainloader +1
  }
  ### END /etc/grub.d/30_os-prober ###

  this will NOT boot windows. "Inavlid signature" error message.

  The original after installation which boots ok looks like this

  ### BEGIN /etc/grub.d/30_os-prober ###
  menuentry "Windows 7 (loader) (on /dev/sda1)" {
  	insmod ntfs
  	set root=(hd0,1)
  	search --no-floppy --fs-uuid --set 90940fdf940fc6a6
  	chainloader +1
  }
  ### END /etc/grub.d/30_os-prober ###
