cannot load image memtest.efi from windows 7

[Greg White]

Hi,

I am trying to load the windows 7 memtest.efi file and grub2 always returns 
cannot load image memtest.efi.  The file location is correct.  What can I do to 
get more information about this error?

menuentry "Windows 7 Memory Test" {
  search --fs-uuid --no-floppy --set=root 4396-78d9
  chainloader (${root})/EFI/Microsoft/Boot/memtest.efi 
}

Thanks,
