Q&A site Simplehelp has a novice-friendly tutorial that shows Mac users how to install Ubuntu Linux.

You’ll need three items: an Intel-based Mac, the Ubuntu OS (a free download, natch) and the latest Parallels build. (For the uninitiated, Parallels is virtualization software that allows Intel Macs to run other operating systems.) The tutorial shows you how to set up Parallels for Ubuntu, run Ubuntu for the first time and “tidy up” the installation (adding drives, sound, etc.). Every step includes a screenshot, so there’s little room for confusion. It’s a great primer for Mac users who want to take Linux for a spin but don’t have a clue how to get started. For more Parallels-driven goodness, check out Adam’s feature on running Windows and Mac apps side by side.
