Hello, thanks for the information in the article! I am trying to put a 2nd partition on my hard drive, and install windows on it. I am running El Capitan, which is a bit behind Mojave. My mac is a late 2008, and cannot go past El Capitan. It also will not allow me to use Boot Camp assistant to install Windows via USB, it must be from an optical drive. I just read your article on installing windows w/o Boot Camp, and it looks very promising for me, however this program (Unibeast) looks like it requires Mojave. Will it work with El Capitan? Thanks for your help!
Upon completion of the USB formatting, locate Install Mac OS X Mountain Lion.app (downloaded in step #1 to the Applications folder, by default). Right-click the file and select Show Package Contents. Due to the smaller worldwide user-based percentage, Mac OS X users are the ones who would likely stumble into these file format problems. If you are a Mac users, here are overviews of different file format systems, and how to choose which format to use for your USB drive to ensure compatibility with other operating systems.
