Title:
  grub2 does not automatically recognize/add windows 7 from gpt
  partitions

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  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 
  }
