[CentOS] Bootable RHES CD

I am using Sonic Digital Media Plus v7, on Windows, and I'm trying to make a bootable RHEL IA 64 bit CD (mostly so I can include a kickstart file).

So what I did is I grabbed the disk one ISO file, copied the contents on my hard drive in a folder.

Then I clicked on the Data -> Data Disk. I then clicked on the "Add Data" button and when the "Select files and folders to add" box popped up, I selected all the files and folders and clicked on "Add".

The window showed all the files. I then pressed "Make bootable" and selected the file, boot.img in the Images folder.

I then burned all this onto a CD-R.

I still can't boot off of this CD. Any hints?

I've done this with CentOS, a long time ago, but maybe I'm missing something. === Al
