You burned CD image file to CD with Roxio Creator DE. But your computer does not take it as image. Roxio’s help file does not provide instruction on how to burn a CD image. Maybe it is too obvious. However, I used “Data Disc” option twice before I figured this out.
You should not treat the CD image as data file. Roxio has a special feature called “Burn Image”. That’s the button you should select. Then you just follow the on screen prompts, which are the same as burning other CD.
