My CPU is 64 bit, I have a PS/2 keyboard and a PS/2 mouse and I have tried Live CDs of Ubuntu, Kubuntu, Fedora, Arch Linux, Wubi installations, 32 and 64 bit (my CPU is 64 bit) and Puppy Linux. I am able to navigate between the menu options when there is one, but when I boot, the keyboard and mouse stop responding. Puppy Linux booted completely, but the keyboard and mouse didn't respond. Besides, pressing NumLock, CapsLock does nothing.

Note that Windows doesn't have this problem.

My keyboard and mouse work flawlessly in Puppy Linux 3.01, but don't in 4.x.

IMPORTANT: I can confirm that keyboard and mouse work in Ubuntu 8.04.4 LTS with linux 2.6.22-14-generic, but DON'T with 2.6.24-29-generic.

So does "keyboard stop working" or "num/caps lock stop working" or the "machine stop working" after you select the boot option? Does it boot, but they keyboard is not responding? –  alex Jul 16 '11 at 11:27
    
@alex I have edited the question; the fact is that the keyboard stops responding after choosing the boot option. –  Juanlu001 Jul 16 '11 at 23:05

There may be an option in your BIOS something like "USB device emulation" - try toggling that. It may be conflicting with the Linux drivers for some reason. It allows older OSs to see USB keyboards/mice as PS/2 devices.

You need that option ON if you have a USB keyboard, or you won't be able to interact with grub. –  psusi Jul 16 '11 at 1:02
    
@Aaron I have looked for that option, but my BIOS doesn't appear to have it. Anyway, my keyboard is a PS/2 one, so I don't understand what you meant. In any case, thank you for your answer. –  Juanlu001 Jul 16 '11 at 9:14
