The boot process first loads the startup configuration from non-volatile random-access memory (NVRAM) into random-access memory (RAM). It then locates the Internetwork Operating System (IOS) using the bootstrap process and loads it into RAM. Finally, it performs a power-on self-test (POST) to check for any hardware problems.
