How do i burn an .ISO file?

An ISO file is an image of a CD or DVD and contains everything a disc should contain inside that one file, kind of like a .zip file.

A common mistake for people and often frustrating to them, is they burn it and can't run the program or software that the ISO was for. This would be because they have only burnt the ISO file directly to disc with the data disc function. Burning the ISO in data disc mode only burns the whole of the ISO file to the CD/DVD. What you want is to use the burn image or burn ISO function in burning software, this adds the additional step of unzipping the ISO and burning each file contained inside the ISO onto the disc, making it operable as the software CD or DVD rather than a CD or DVD with an ISO file.

Summary: Your burning the ISO file itself not the files contained inside the ISO.

Burnaware has a good, easy and simple ISO burning tool but it is no longer available as seen in last post.
