Ubuntu Installation :: Can't Install 10.10 Desktop Version

I'm trying to install the desktop version on my laptop but i'm having an issues. I wrote the .iso file on a CD and restart my pc to boot. So -> the pc founds the medium, i'm choosing the language, i'm choosing "Install ubuntu" and nothing happens. The dots srarts to blink and that's all. When i press anykey opens an cmd promt (something like that) and there's a lot of errors - for example: ... file failed to open due to unknown user id", some files are missing and so on. I tried "try ubuntu without installing" but the same thing. I hear a sound (i guess this the "srart sound" of ubuntu) and that's all. The orange screen, the icon in the middle and the blinking dots. I made two CDs - one burned with win 7 integrated soft - right click and "burn disk image", and other burned with infra recorder. Nothing changes.
