From where can the boot option be selected?

The boot option can typically be selected from the computer's BiOS or UEFI firmware settings. To access these settings, you usually need to press a specific key (like F2, F10, DEL, or ESC) during the initial boot process. Additionally, many systems allow users to select a boot device temporarily by pressing a designated key (like F12 or F8) during startup. Alternatively, boot options can also be configured within the operating system's settings.
