[Bug 1073281] [NEW] Invalid Windows entry in GRUB2.00

[Miguel Montargès]

Public bug reported:

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
}
