I have burned Ubuntu 11.04 on CD then installed on Desktop PC, so this CD copy is fine, but I wanted upgrade my 10.10 (Laptop, laptop is fine,too). I have booted to Live (Try without installing) and direct install... both not working... I see just Black Screen. There are no even any processes at laptop.
Try to use 11.04 stable version (not beta). Bad news is unity does have video cards problem. some laptop does not load unity. I failed to install unity on a compaq laptop. Try to google this problem with your laptop model.
