  • You bought the installer disc? I hope you did not pay too much for it... Ubuntu is free open source software. You can download it legally for nothing (or a donation).

  • Yes, I bought the installer disc because our ISP's network speed is slow and not reliable. Thanks bro.

You can install the Ubuntu Unity desktop environment alongside GNOME desktop environment.

Open a terminal and execute :

sudo apt-get update
sudo apt-get install ubuntu-desktop  

Log out - on login screen select Unity - log back in.
To change back to GNOME desktop environment :
Log out - on login screen select GNOME and log in.

Personal note :

After installation of Unity has finished, I recommend to perform a reboot of the Ubuntu system.
