What is the correct order of the traditional Linux boot process?

Question

Accepted Answer

Firmware (BIOS/UEFI) → bootloader → kernel → init/systemd — Firmware initializes hardware and hands off to the bootloader, which loads the kernel, which then starts PID 1 (init or systemd). The other orders invert this fixed hand-off chain.
