I was trying to put a cd burning in my computer and my computer would
freeze up when I clicked on the icon for the burner.

A friend of mine did something to my computer to try to fix it and I
think he really messed it up.

Now I only get a black screen that says

Pri Master HDD error
Sec Slave Drive - ATAPI Incompatible
Run Setup
Press F1 to Resume

but my computer will not let me hit delete at the first boot screen or
hit F1 on this screen..

Can you help me fix my computer....
