Title:
  invalid Windows7 EFI entries in GRUB

Status in os-prober:
  New
Status in “grub2” package in Ubuntu:
  New

Bug description:
  64bits computer with pre-installed EFI Windows 7.

  Installed Ubuntu 64bits in dual-boot. GRUB (grub-efi) is correctly
  installed and allows to boot Ubuntu, but it does not allow to boot
  Windows.

  Its menu shows 2 INVALID Windows entries. When selecting these
  entries, it displays "Invalid EFI file path" error, and returns to
  GRUB menu.

  It's possible to boot Windows from the (EFI) BIOS menu.

  
  ### BEGIN /etc/grub.d/30_os-prober ###
  menuentry "Windows 7 (loader) (on /dev/sda3)" --class windows --class os {
      insmod part_gpt
      insmod ntfs
      set root='(hd0,gpt3)'
      search --no-floppy --fs-uuid --set=root EE00AEA700AE75ED
      chainloader +1
  }
  menuentry "Windows Recovery Environment (loader) (on /dev/sda5)" --class windows --class os {
      insmod part_gpt
      insmod ntfs
      set root='(hd0,gpt5)'
      search --no-floppy --fs-uuid --set=root B2BCAC28BCABE557
      drivemap -s (hd0) ${root}
      chainloader +1
  }
  ### END /etc/grub.d/30_os-prober ###
