AW: Grub2 EFI: compatibility with wimboot

Okay,
wimboot works in Grub2 Legacy for example:

# Successfully boots
menuentry "Windows 7" {
        set ISOpath="/img/windows_7.iso"
        loopback loop $ ISOpath
        linux16 /boot/wimboot/wimboot
        initrd16 \
                newc:bootmgr:(loop)/bootmgr \
                newc:bcd:(loop)/boot/bcd \
                newc:boot.sdi:(loop)/boot/boot.sdi \
                newc:boot.wim:(loop)/sources/boot.wim
}

Because I can not use linux16 in Grub2 EFI, I use only linux but this
creates a blackscreen (with the chaining it does not work either).

I also asked the developers of wimboot they said grub2 could not load EFI
binarys directly.
So I ask, is that the case?

P.S.
I found this maybe this helps:

We are happy to help but first of all we need more info about your legacy
BIOS and UEFI usage. Could you send us your config files, error messages,
etc.?
