CDBOOT cannot boot from CD code:5

Windows 7 professional will not start. When I try a normal startup with the installation disc or the Windows 7 32 bit repair disc I get a message during the startup that says "CDBOOT cannot boot from CD code:5 and I end up in a Windows Error Recovery window. When I click on "Launch Startup Repair" Windows loads files and immediately returns to the Windows Error Recovery Window.
