It's not the same setup as you have. I just unpacked each iso into a subdirectory (and as you can guess, gentoo is unpacked in the gentoo subdirectory). I do not know, but maybe you can give it a shot with `subdir=(loop)`. Also the files are called on my bootstick gentoo and not gentoo64, but my version is also already 1 year old ;) Cheers Andreas
