What is the generic way to create a boot CD for any given Linux distro using grub ? Can anyone give me the exact commands for creating the proper ISO image. From there I know how to burn the ISO image to CD.

Creating a bootable CD itself is a big topic. There are different ways to do it. Using grub on top of that also is slightly non-conventional . Though I have created customized Live CD based on CentOS and Fedora but using ISOLINUX as boot loader. But it can be modified using grub as well. Following are the links that I have used to create Live CD and Grub bootaable USB linux installers.

I can not believe that there is not a simple single way to create a boot CD using grub for any generic Linux distribution. is grub in each and every distribution radically different so that there is no common way of doing it ? If that is truly the case then I will ask this question on the appropriate forum for each Linux distribution for which I need a suitable grub boot CD.

for which distro , are you trying to create boot CD ?

The command below (from the Gnu Grub page, see link below) will create an iso file named grub.iso to include all files in the directory below isoimages, run from the directory above isoimages. Obviously, either of these names can be changed to what you want. You will need the stage2_eltorito file to boot a CD. The distribution is irrelevant. See the link below:

mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot -boot-load-size 4 -boot-info-table -o grub.iso isoimages
