Hi David, Sorry I was AWOL for a while - other tasks were calling. Follow the advice of Greg. He is the installation expert.
And when you are done installing, you must make images. Then you are safe for whatever happens. Any event from which the system can go on the blink (simple crash, a virus, a damaged disk) and you can restore the system from the image. An image can be restored in 20 minutes - beats reinstalling and all the hassle.
You do, however, need an external disk, but it is worth it. I recommend free Macrium. Here is a little tutorial I made: Imaging with free Macrium
When you are ready, post back and I will help you set it up.
