Is there any way to have the setup files for two different versions of Win7 on a USB flash drive? I would like to have a universal USB-install-drive that contains the German version and the American version. And when I want to install with this drive it should ask me which version i want to choose. Is that possible in an easy way? Ah and I know that I could integrate or install the language packs, but I would like to know if its possible the way I'm asking for.
