Hi, I'm a user of YUMI, and I'm looking to include two versions of windows 8.1 installer on the same YUMI installation, but apparently, it only supports a single windows installation of the same version. So I am thinking of creating one ISO that consists of two isos (x86 + x64) combined together. I've searched and looked at the stickied post regarding creating a Windows 8.1 AIO installer, but it's too confusing for me, and I don't understand it at all. I'm only trying to combine two ISOs, but the stickied guide provides for around 8 ISOs (?), which I can't make out on how to proceed with mine. Can someone please teach me how can I do this? Help is greatly appreciated. Thanks in advance! Cheers, L.
