It's one of the longest running unintentional gags in computing. The computer can't really operate without a keyboard (a mouse can only get you so far), so when your keyboard isn't detected, there's really nothing that can be done. However, this error message sometimes comes up when it shouldn't, so it asks you to press a key on the keyboard (F1, in this case) to prove it wrong.
