I was actually using the distro on Oracle's website. They have recently upgrade the site, and they have one iso.image on a DVD and I have five iso.image on one DVD. I think the computer does not know which image to boot from. So, I'm going to download each image on separate CDs as follow:
Installation
To install Enterprise Linux from the ISOS, follow the steps outlined below:
1. Download the compressed binary CD images
Download Enterprise Linux 5.1 discs 1-5 from Oracle eDelivery. You do not need to download discs 6-9 to install Enterprise Linux, these CDs only contain the source code.
2. Uncompress the CD images
The downloaded files are compressed with the zip format. Use any unzip tool to uncompress the file, or download a utility from eDelivery

3. Write the CD images to CDs
Use your favorite cd burning software to write these images directly to CD. Do not write the image files to the CD. To test if you have burned the images correctly, insert a burned cd and ensure that multiple files and directories are visible.
4. Insert the first cd, and boot
Lastly, insert the first disk into your system, boot from CD, and follow the on-screen instructions to deploy Enterprise Linux!
To install Enterprise Linux 5.1 from the DVD media, follow the steps outlined below:
1. Insert the first cd, and boot
Insert the DVD into your system, boot from DVD, and follow the on-screen instructions to deploy Enterprise Linux!
Note: Iif you intend to use the graphical environment either select the full install from the installation menu or ensure that kdelibs is one of your additional selected packages.
