It is advised to check the md5sum with the freeware Md5summer or winMd5Sum. It will save you a lot of hassle to check it, especially if you are a newbie. That way, if anything is not working well, you will know for sure it is not your original ISO image which is corrupt, since you will have taken the step before the burn process to check the integrity of the ISO image with Md5summer (or any other md5sum software) (see wiki for md5sum details).
Your chances of getting a good cd are increased by using a slower burning speed. If your cd doesn't work after burning, make sure you have done the md5sum check above and then try a slower speed.
If you have Roxio on your computer, double click the iso image file (or right click the iso imageif the wrong applications is launched - some people have many CD burning applications.). Roxio Disc Copier will launch, ready to burn the iso file (the right menu will have been selected by Roxio automagically). Insert a blank disk, and press burn (the orange icon with a CD in flame).Whichever software you use to burn the ISO, when you are done, you have a Linux CD. Repeat with other images if the distro has more than one CD.
