It seems that existing guides of how to boot from USB are out of date, and the one here (https://learn.adafruit.com/external-drive-as-raspberry-pi-root/hooking-up-the-drive-and-copying-slash) didn't work, as it didn't alter the root, though it copied all my files to the SDD.

I don't want to mess up any important files, as I don't know much about them. Is there any up-to-date tutorial for a beginner?

  • What Raspbery Pi model you are using? Is it a RPi 3B+? – Ingo Mar 25 '19 at 18:02
  • It seems that existing guides of how to boot from USB are out of date no, they are not, of course, depends on what you're reading. Going to AdaFruit to get instructions on raspberry pi is like going to a driving instructor to learn how to fly a jumbo jet. With respect to AdaFruit, they barely know their own "products" so, you're not going to get any useful information about something they didn't "make" – Jaromanda X Mar 26 '19 at 1:41
  • @Ingo, yes, it is a Raspberry Pi 3 Model B+, from the box. Do you know of and recommend a guide that works without any in-depth technical knowledge? – user96931 Mar 26 '19 at 15:10
  • Hmm. I found a topic here (raspberrypi.org/forums/viewtopic.php?p=1385780) and the third post seems to fit my needs. I'll update this if it works. – user96931 Mar 26 '19 at 15:17
  • Ok, I've got it working now :) – user96931 Apr 30 '19 at 20:07

The Raspbberry Pi 3B+ has improved boot capabilities. It can boot from any USB drive out of the box. Just flash an Raspbian Image to the USB storage like you do it with a SD Card. Put it into one USB port on the RasPi and boot. The only thing is that there must not be a SD Card in its slot. The RasPi will always first boot from it if it find one.

  • Except that it's not any USB drive, just some USB drives. – ccpizza Aug 17 '19 at 8:51
