can't get 11.04 to start
I am a total noob at using linux so please forgive my ignorance. I made a live cd of ubuntu 11.04 using bit torrent and infra recorder. After booting to the cd, a screen that says "Ubuntu" in large orange letters appears with options such as install ubuntu, try ubuntu, test memory, etc.... When i click on the option to either try ubuntu or install ubuntu, i can hear the cd drive spin for a moment, then it stops and nothing happens. I would just like to know if there is a step I am missing, and i appreciate any help or advice you guys can give me. thanks!
I have a dell d610 laptop with i believe 500 mb of ram. currently i am running windows xp 32 bit with ntfs.
