Title:
  os-prober fails with chainloader on win7 partition

Status in os-prober package in Ubuntu:
  Confirmed

Bug description:
  os-prober detects win7 partition and creates menuentry with chainloader+1 (see http://paste.ubuntu.com/10696096/),
   but loading win7 ends in black screen without returning to GRUB2 menu.
  modified separate menuentry "11_Win7-Loader" (see below) in /etc/grub.d/ using ntldr instead works pretty well, 
  after disabling OS_Prober in /etc/default/grub: GRUB_DISABLE_OS_PROBER="true"

  menuentry "Windows7 (loader) on sda2" --class windows --class os {
  	savedefault
  	insmod part_msdos
  	insmod ntfs
  	insmod ntldr
  	set root='(hd0,msdos2)'
  	search --no-floppy --fs-uuid --set=root DEF2805CF2803B33
  	ntldr /bootmgr
  }
