Booting to command line can be selected using the raspiconfig tool, submenu Boot Options. The user should get something like this 10-quirks.conf 40-libinput.conf evdev.conf 99-fbturbo.conf 45- $ sudo raspi-config 5) 10) Shutdown the Raspberry Pi safely, and remove the power after it has completed its shutdown.
