I want to make a live disc of a Linux operating system, so I downloaded the “ISO” of Ubuntu 7.10. After downloading I used “ISO Buster” to extract the files. Then wrote them on to a disc. But, when I tried to boot form the disc the computer goes ahead into my second boot option which is the hard drive, skipping the CD. I tried both the x86 and x64 versions. And even tried it on another computer nothing seems to help. Am I doing something wrong or is it just the disc?
