Well, it's not exactly what you were looking for, but I do have some advice for you yes: stick with a dual-boot Linux/Windows setup. I've used Linux as my primary operating system for more than a decade, and that entire time it's always been a dual-boot setup. For better or worse, Windows is virtually everywhere, and there are always little things that you end up needing it for. Games in particular.Also, Backtrack is more or less the same as Ubuntu. Just has a few different customizations -- like the color of the windows I mean -- and a bunch of security related packages come preinstalled. Ubuntu is Linux is Slackware is Fedora. They're just different flavors of the same kind of candy; unless you have specific needs that are met by one or the other, you're better off sticking with what more people use (which means there's more help and more active a community around the distro).I found linuxquestions.org rather helpful when I first started using Linux. Try over there. I'd help you out, but frankly I don't have a bloody clue what dongle you're even talking about let alone whether Ubuntu comes with a compatible driver.
