1. We'll assume you have already downloaded the .iso file, and that you know where the file is sitting on your hard drive.

2. Go and grab a free CD Burning program if you don't have one that you know how to work, we are currently recommending an easy one, CDBurnerXP http://cdburnerxp.se/

3. Now you can tell CDBurnerXP to "Write ISO" and you'll get a screen asking where you put that file you downloaded

4. Start burning.

Now if this goes as planned, it was that easy to make your disk from an image, and you can probably put that disk in your computer and reboot if it was Windows - it will install right from there.
