Use your favorite burning software to burn the iso image to cd. I like
ImgBurn for windows because it is free, easy, and effective. Once the cd is burned, put it in your pc and reboot. Enter into your pc bios and change the boot order to making the cd drive the first to boot. Normally to get into pc bios, you need to press one of the following: del, f2, f10, or f12. It depends on the pc but it is normally right after the pc starts and it will say on the screen which one to press.
Once you get it booted on your pc, put your device in DFU mode (hold both volume buttons along with power). Plug in your device, click the green android icon on the desktop, press ok or enter on the password prompt, type "stormer" which is the codename for your device (you will see a chart) and press enter. Confirm with "y" then press enter, and wait.
Personally I make bootable usb flash drives instead of cd's. There is a program called
Unetbootin that makes the process very easy.
