How to access/enter BIOS mode on your PC or Laptop

PC, there is a very short period, when the
BIOS entrance command appears on the screen, but if you miss the moment, you will have to start all over again. If you know, what the keys combination you should use is, you need to execute it immediately upon computer reboot, and sometimes it requires multiple repetitive clicks to activate it.
