I didn't have a clue either when I was presented with an ISO .But I had seen the section in NERO so ,I went ahead and tried it and it worked first time. MarkLister uses Ingburn in the previous post ,I'm afraid I dont , but ,I know NERO will do the job .Just tinker around with Imgburn untill you get it right .
It should work , like I say , this program is well worth having if you have PC problems , everyone swears by it , so persavere till you get it m8 .
