Press any key to boot from the CD

Yes, the title is the message I get when I have to format the computer. It is also good enough, but why does it keep yelling on?? Wanted to format my little brother's computer the other day and got the message. It would not cooperate and started just plain up.

Coming so I remember that before there was something similar with other WorldCom I've formatted. When the keyboard is set to the machine via USB so it cannot boot from CD! What nonsense! But ok, I got an old board with Serielstik and put my brors com .... VUPTI ..... So it would like to start from the CD ????? Here is my question-

Why should it use a board with Serielstik to do what is being said?
And now lets not say that it is like that only, for it does not happen on my own machine. It starts fine from the CD when I press a key. But the second makes no sense. But but but, with so much else there are probably explanations :)

The short explanation for the long question is that :D USB keyboard support will most likely be disabled in the BIOS. You can enable it from bios using a PS2 keyboard and then after, you can always boot from CD using the USB keyboard.

Oh Ok. I will be exploring :)
Thank you for your reply.
