Old man trying something new

I have a simple .iso file already on my pc. I want to know how to put that .iso file onto a dvd and make it bootable (it is a windows vista 32bit OS installation .iso file) using Nero Express. It is not an image file, but it is already an .iso. I am sure it will be fairly simple, and it will probably make me look like an idiot, but I want to be sure, and what better place to ask than this forum.
