Hi, I have been trying without much success to install W7 to an HP Proone 400 G2 (i5-6500). It seems the problem lies with missing USB drivers. This means that when the install reboots and you are prompted to name the pc etc, you have no mouse or keyboard input. I have patched a W7 install using the Intel software but all this did was remove keyboard/mouse support from the start of the install too, which led me to think that maybe the drivers were incorrect for this model. Maybe I was doing something else wrong though, I'm a bit stumped here. Any help would be greatly appreciated.
