Make your Raspberry Pi quicker and more reliable
Let me know your device and whether or not you succeeded in the comments. I’ve tried this using a Raspberry Pi 3 and had success using both Corsair Voyager 3 and Toshiba Flash USB flash drives. This method of booting is experimental and won’t work with all USB Flash devices. There’s a Windows version of this tutorial, check it out over here. You will need a good quality USB Flash Drive, a USB MicroSD card and a Raspberry Pi (I’m using a Raspberry Pi 3 with WiFi). This guide will help you through the steps necessary to install Raspbian (current version at the time of writing, Raspbian Jesse) onto a USB Flash drive from MacOS (OS X) or Linux (ie Ubuntu).
