Title:
  Invalid Windows entry in GRUB2.00

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu12.10 and Windows7 dualboot.

  Default Windows entry in GRUB menu fails to load Windows
  Code:
  menuentry 'Windows 7 (loader) (sur /dev/sda3)' --class windows --class os $menuentry_id_option 'osprober-chain-CC0CC8FE0CC8E494' {
  	insmod ldm
  	insmod ntfs
  	set root='ldm/f4f4081f-1997-11e0-809d-0022fb714c30/Volume1'
  	if [ x$feature_platform_search_hint = xy ]; then
  	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0 --hint-efi=hd0 --hint-baremetal=ahci0 --hint='ldm/f4f4081f-1997-11e0-809d-0022fb714c30/Volume1'  CC0CC8FE0CC8E494
  	else
  	  search --no-floppy --fs-uuid --set=root CC0CC8FE0CC8E494
  	fi
  	chainloader +1
  }

  The following custom entry is able to boot Windows:

  Code:
  menuentry 'Windows 7 on /dev/sda3 MANUAL' {
     insmod part_msdos
     insmod ntfs
     set root=(hd0,3)
     chainloader +1
  }
