[ubuntu] Ubuntu does not boot in Alienware M14xR1, just black screen

view story

http://ubuntuforums.org – I have a Alienware M14xR1 with 16 gigs of ram and nVidia GT555M with Optimus + Intel HD3000. I installed my Ubuntu from a USB stick to another USB stick. Did not use the startup disk utility, and literally installed it on the USB stick after wiping it with diskpart in windows. I have a need for Installing Ubuntu on USB, not a LiveCD Startup disk or installation on the HDD. When I try to boot it normally, it won't boot. No boot splash screens, no reports. No crashes, or something. Just a plain black screen. However, LiveCD USB would boot well. I put into some efforts with trying some answers (Hardware)
