[ubuntu] Trial from CD works but will not finish boot.

view story

http://ubuntuforums.org – I'm having a bit of a conundrum with 12.04. I put it on a CD to install it on my new system and tossed it in. Checked out the trial bit and everything seemed to be ok, it looked great. So I do the actual install, restart, and... I get a purple screen. If the trial works then why will it not boot properly? :???: 'Edit'- Forgot to say its the 64bit version I'm trying to use. System is this: CPU: Phenom II x4 Mobo: Gigabyte 990FXA Graphics: Sapphire Radeon HD 6950 HDD: 1TB Seagate Barracuda RAM: 8Gb Oh, fresh meat by the way. Hey all!):P (Hardware)
