Right now, GRUB4DOS/ntldr-img requires BIOS facilities, so even in principle it can't work on a full UEFI system (although most current UEFI systems have some degree of compatibility, but it won't stay that way forever). If the Windows UEFI boot loader is loading .efi files, though, that sounds like it has a different interface which might actually be easier to support.

I agree that we should at least warn.
