So i just built my own computer. I have the hard drive reformatted and i have a disk in to download windows xp. When i start the computer however, when it starts loading up i press f2 on the screen it tells you to to go to the boot menu but it doesnt work. Then it takes me into a screen saying "reboot and select proper boot device or insert boot media in selected boot device and press a key." I can see why that would happen but i have tried 3 different keyboards and none have worked, any help on this?
