[Bug 1007923] [NEW] grub2 does not automatically recognize/add windows 7 from gpt partitions

[Fizzfadlt]

Public bug reported:

Expected to happen: sudo update-grub should add windows to the grub menu, using the menu option would boot into windows 7
What happened instead: sudo update-grub does not recognize windows

Windows 7 (as well as Ubuntu 12.04) is running on the same hard disk
with a GPT partition.

I was able to manually add windows using the following menuentries (both work, only one is needed) to
/etc/grub.d/40_custom

menuentry "Windows" { 
search --fs-uuid --no-floppy --set=root E20F-0E2C
chainloader (${root})/efi/Microsoft/Boot/bootmgfw.efi 
} 

menuentry "Windows" { 
insmod part_gpt 
insmod fat 
insmod search_fs_uuid 
insmod chain 
set root='(hd0,gpt3)' 
search --fs-uuid --no-floppy --set=root E20F-0E2C
chainloader (${root})/efi/Microsoft/Boot/bootmgfw.efi 
}
