I have 3 OS in one computer. and I can't choose The OS with a wireless keyboard? any help?
Might have to turn on support for USB keyboards in the BIOS. During boot-up it'll flash up which button to press for setup. Depending on the manufacturer of your computer it could be the DEL key or F12 or something else entirely.
Most motherboards do not recognise USB connected keyboards until the OS loads. You may need to get a ps2 connection keyboard or an adaptor for your keyboard.
