It's what I thought. Your keyboard does not work. Why, you can ask me, 
if it works on my system? Yes it does work!

The actual facts are that you're controlling grub menu with an usb 
keyboard even if you do not have one.

Grub does not have any keyboard driver, it only reads the keyboard that 
BIOS present to it. So... if you have a USB chip somewhere in your 
computer your BIOS sets your keyboard as a USB one and voila... here's 
the problem.

So you can try it if you want to... you plug in an usb keyboard to your 
computer and you will see that it works.

How to fix it?

You have to go to the BIOS and setup it so that the option: USB KEYBOARD 
ON (or similar name) is disabled instead of enabled.

This way the BIOS will try to search for a ps/2 keyboard and it will 
find yours... and you will be able to use Grub's menu.
