I have a friend's daughter that I upgraded an FX setup to a new ryzen one. She has windows 7 installed with a ton of games and other stuff in place that boots perfectly fine. I just have no usb input (the board doesn't have a ps2 port) because of ryzen's lack of support. Is there a way I can install them without injecting the drivers into a win 7 iso and have to reinstall again? Whether it be using another computer, putting the drive in a dock, or even setting up something that will auto run when popped into the dvd drive.
