The most common hurdle for inexperienced users is accessing the boot menu. This requires precise timing. Upon powering on the computer, the user must repeatedly tap a specific keyboard key—often F12, F2, F10, or Delete, depending on the manufacturer—before the Windows logo appears. This interrupts the standard startup sequence and launches the BIOS/UEFI interface. In this environment, the mouse rarely works, and navigation is handled via arrow keys.
