I know this is a rather lame question, but. I want to do a system recovery on a dying laptop, (compaq with XP) about 6 years old now. When I get to the screen giving me the choice of starting the recovery I am prompted to enter f18. The function keys on my keyboard go up to f12 and I cannot for the life of me figure out what key I need to hit in combination with another to get f18. Anyone know?
