Why don't I get the black and white message after restarting the comp

My disk is only allowing me to reinstall on a bootable drive. Why don't I get the black and white message after restarting the computer that I need to hit any key to open up the disk so that I can install on a data only disk. My computer does not recognize my Windows 7 auto function. My boot sequence(CDROM and HD) has been changed several times without correcting the problem. I had a code 39 problem earlier indicated in contol panel and corrected the problem only part way.
In the past I have had two ways to install windows 7 since Oct 08. Something is wrong with my computer. Please help!!!!!

If the DVD/CD player is listed first in Bios and the windows Disk is good and the DVD player is good. The below picture automatically comes up.
One of the three previous items I listed is defective or out of order.
There is no registry key. Windows is not operating yet as it is not installed when trying to boot to disk.
Your Bios is in control until the below screen is initiated.
Fix the disk or DVD drive or boot order and it will work. Nothing else is involved. Disk, bios and DVD drive.
Clean Install Windows 7

Most newer computer provide a Fn key (often F12) you can press during boot to get to a boot device selection menu. From there you should be able to select the DVD drive to boot from.
