How Install ubuntu 10.04 on a DELL N5110

I am tried to install Ubuntu 10.04 on a DELL N5110, I have Ubuntu 10.04 LTs CD. When I try to booting from CD, the indicator light on my CD-RW drive keeps blinking during boot, after that, the screen get a hold black and it cannot install or continue.
Do I need to change any settings on bios before install?
