The Linux boot process starts with powering on the computer. The entire purpose of the boot process is to load the Linux kernel into memory and start either init or systemd.
The boot process can be initiated in one of a couple ways. First, if power is turned off, turn on the power to begin the boot process. If the computer is already running a local user, including root as well as unprivileged users, can programmatically initiate the boot sequence by using the GUI or command line to initiate a reboot. A reboot will first do a shutdown and then restart the computer.

The first thing that takes place upon boot or reboot is that the hardware runs the BIOS POST, or Power On Self-Test.
