Boot a RPI Zero from your laptop without SD card Now they came up with USBBoot, a tiny program that pushes the bootcode over the USB to the Raspberry Pi Zero (Raspberry Pi model A, Compute Module, Compute module 3 and Raspberry Pi Zero and Raspberry Pi Zero W), so it can boot without a micro SD-card. Luckily the great minds of the Raspberry Pi Foundation developed new boot modes: ethernet boot and USB Mass Storage Device (MSD) boot for the Raspberry Pi 3. Still the RPI Zero was using a micro SD card. In an earlier post I explained how you can run and connect to a Raspberry Pi Zero with just an USB cable.
