Yesterday I installed my new wireless keyboard & mouse (Microsoft desktop 8000) & restarted. When I turned the pc back on, it just hangs on the dell bios screen, with the F2 & F12 options, and the keyboard doesnt do anything when you press these.
Plug in my old wired keyboard & it boots up! No keyboard or wireless adapter plugged in and the system will say keyboard failure.
So it doesn't boot up because it cant detect the wireless keyboard, but the wireless keyboard doesn't become active till windows is booting, is there a way to stop the bios from checking for a keyboard and allow the system to boot up?
