I have developed two different startups which switch one to the other each time I startup.. One starts as normal ie. Press power on, first screen says Press <F2> to enter startup.I do not press F2 and startup proceeds to coloured Win circling stars and all is well. Win then shuts down as normal on command. Next time I Press Power on, first screen says Press<F2> to enter startup. Screen hangs here for ever. Pressing <F2> does nothing. I need to power off to clear screen. Next time I start the normal start happens.I can press F2 and get the normal startup parameters screen Next time I start the hang happens. Pressing <F2> does nothing I can see. And so on ad nauseum. Restoring to earlier time has no effect. I have been unable to fix this and have resorted to powering on twice every time.
