First, make sure that you have downloaded the correct files. For each distribution there are binary files and source files. To complete an installation the four binary files for a particular distribution are required.

Simply burning these files to CD as files will result in a single file being burnt to CD with a .iso extension. If this occurs your disks will not be bootable. The files available from Red Hat Network (RHN) are disk images and need to be burned to CD as an image.

Your burning software will extract the files from the .iso and burn them to CD
See your specific burning software documentation for more information on how to burn images to CD.

To check if you have burned each image correctly simply examine the contents of the CD. Instead of a single .iso file the disk should contain multiple files and directories.
