It's quite simple really. As long as your case has room, simply install the new harddrive into a free 3.5" bay. Proceed with installing the harddrive. Format and partion your new drive. Get it to where you can access it in windows and simply transfer everything over. Hope that is what you are looking for. If you do it this way, you can keep using your old harddrive as well, or simply transfer all of your old files onto the new drive. I think I covered it.
