It's not expected to work in all cases. Nothing wrong about that.
Is using some non-beta an option?
After a little run in with Ubuntu, my friend said that I should give Windows 7 a try. He gave me his flash drive, and I installed it without issues. It works marvelously with one exception: I can't get Direct3D to work. It says that I am running DirectX 11, so I figured it might just be that it's buggy, and I installed DirectX 9. No effect. The only help I get from dxdiag is Direct3D -- Not Available.
