Only the custom system installation gives you complete flexibility. You have complete control over the packages that will be installed on your system. You can also determine whether you will use GRUB to boot your system. Unless you have prior Linux experience, you should not select the custom-class installation method.
For more information concerning the differences among these installation classes, refer to the Red Hat Linux Installation Guide.
