To make or as it's called burn the recovery CD you need a software program that burns CDs.
If you don't have one already we recommend ImgBurn.
It's free and will easily create the recovery CD using the ISO image file we've provided to you.
Download and install ImgBurn from here: http://www.imgburn.com
Simply load a blank CD into your CD or DVD tray.
Then launch ImgBurn and select the "Write image file to disc" option and simply follow the instructions.
