I, like millions of others, use Mac OS X as my main operating system. It’s fast, reliable and secure, and the computers it runs on are undeniably the best designed and built machines available on the market. There are many options available to users who need the added flexibility of running Linux or Windows alongside OS X, perhaps through SSH or by using a Virtual Machine. Sometimes, though, you need a full, non-virtualised OS environment to work in, and while Boot Camp is great it’s not ideal for someone like me who rolls with a very fast, but very small, SSD boot drive.
In this tutorial, I’ll show you how to install Linux to any external USB device and boot your Apple computer from it. I’ll be working with Ubuntu 11.04 32-bit and a MacBook Pro running Mac OS X 10.6 Snow Leopard. Guides elsewhere online seem to only help you if you happen to already have a Linux box to work with – my tutorial only requires one Macintosh computer. All the software used herein is open source and free of charge.
