Are F2 and F12 valid boot options for your computer? If not, you'll get this error or a keyboard stuck error. Normally during post you should see something like F2 - Setup or F12 - Boot Option. Some computers use the DEL key or some other key.
yes they are valid during post f2 & f12 come up but clicking on either one next screen comes up and says keyboard failure...formated hard drive a few days ago
installed every thing from disk worked ok next morning turns on but will not boot up
tried DEL key still does not work
