HP Laptop won't boot from CD/DVD Drive through BIOS?

[Disisnot]

I've been wanting to install Back Track 5 R3 (Linux OS) onto my laptop for quite some time now. I am using a DVD to install it and it works fine on other computers. I believe the problem is with my BIOS, because when I select boot from internal CD/DVD drive, the Windows OS I already have starts up as it normally would. What is the problem?

enter the cd
restart the pc
enter into bios

To Enter the BIOS press the "Del" button on your keyboard. Alternatives are "F1", "F2", "Insert", and "F10". Some PC's BIOS might even require a different key to be pressed. Commonly a PC will show a message like "Press [Del] to enter Setup" to indicate that you need to press the "Del" key.
