your best bet is try find the version you want and duel boot. this way you can always go back to windoze if you get confused or something doesnt configure the right way.
another big help is searching this site. i've been on here for some time but have a nice low post count because all i ever do is search. just remember to have fun and if something doesnt go your way, dont run, try to figure out why. after you understand it you'll be glad you stayed.
