I don't know what has gone wrong, is it my CD or is it my system? When I try to install Ubuntu on my system, the installation process freezes at 'Preparing to Install'.

I really like to play Team Fortress 2. But I have installed Ubuntu 14.04 on my system since I don't have a license of Windows 7. I tried to run TF2 from terminal and I got these errors:
