Using Windows Disc Image Burner
Using third party software
If you are on an older version of windows that does not have Windows Disc Image Burner then you can install some third party software to allow you to do this, there are many options to choose from but the one I will use for this tutorial is ImgBurn.
Download and install the ImgBurn software from the ImgBurn Website at http://www.imgburn.com/ and make sure when you install it to uncheck the ask toolbar option, this is an extra accessory that you do not want nor need.
Once the software is installed and ready to use burning an iso uses a similar process to the Windows Disc Image Burner, just right click on the ISO file and click Burn using ImgBurn.
A screen will be displayed allowing you to choose which drive to burn to and then burn the image to disc.
