OK just some newbie questions.... Cont

Sorry to do this but it wont let me reply for somereason

Anyway I downloaded a game and extracted it. It turned out to be a CDRWIN/FIREBURNER image. I have burnt this to disk and it does nothing. It tries to read from the disk but fails. This also happens with Utopia Boot Disk. I am thinking its just the cheap CDs.

Secondly can I copy backup disks? So can I create an image of backup CD and burn it off to have another working version?
