There’s lot of info on the Internet about how to install Windows 7 on Ryzen CPU system using USB bootable pen drive. Some motherboard manufacturer have even released utilities to do driver patching for Windows 7 bootable pen drive. However I am bit confused about the technicalities of the same so have some basic doubts! 1. Is driver patching needed if I am going to install Windows 7 using SATA internal DVD drive and Windows 7 SP1 bootable DVD? 2. If my AM4 motherboard offers USB 2.0 port, would Windows 7 on Ryzen fail to detect even USB 2.0 port? 3. If so, does the chipset driver from the board manufacturer take care of the USB 2 detection later once Windows 7 is installed? Thanks.
