This is a gem: Easy Linux tips project. It’s a set of detailed yet simple instructions for migrating from Windows to Linux. You get to choose between several different Linux distributions all of which are the easiest to use and each offers long term support so you don’t have to reinstall or upgrade every few months: Mint, Ubuntu and friends, and Peppermint. I stumbled across it when seeking the best advice for migrating your Windows email and settings over to a Linux system. I already knew, of course, but didn’t want to have to write it up myself. This one is about as simple as it gets.
While it’s not as if I would do everything just the same as this site suggests, it’s close enough. If you area considering migrating from Windows to Linux, I recommend this one as a decent source of information on what’s involved in the process.
