Hey, I recommend you start to learn this way: Install Debian on your PC. Install Easy Debian. Then always take a glimpse at Debian User Forums threads. You'll learn many things over there. But, don't ask noob questions there, search Google, or ask me in private, because they'll react in a bad way if you ask noobish questions in public forum. I'm willing to help you though. And please, call it GNU/Linux. Because the OS is GNU, just the kernel is Linux. Good luck mate!
