Many people are put off using Ubuntu because of installation issues. Not that installation is difficult, of course, but for the true non-technical user, it's equivalent to scaling Mount Everest.
This guide is for them. It's a step-by-step guide to installing Ubuntu for complete and utter beginners. If you have a relative, or friend, who would like to try Ubuntu, but who is frankly scared of the prospect, then send them a link to this posting! It assumes zero prior knowledge.
