Once you boot with the Live CD you will be prompted what Language to use during the installation process. As you can see there are many languages supported. Select your preferable one and hit Enter.
Wait a while till the installer boots. This is Ubuntu' s Welcome screen. Here choose the language that will be used during the installation process and which will be the default language for your final system. In the next window find your city in the map, or a city closest to yours, to adjust your system's Time Zone and Current Clock Time. Next select your keyboard layout.
Next type name and login name as long as your login password. Also give your computer a name and select to Log in automatically if you are the only one using this computer and you don't want each time to type your password. And now you are ready for the installation process to begin. Just press the Install button. And the installation will begin. It shouldn't take long. About 15-20 minutes depending always on your computer's hardware. Once the installation is completed press the Restart now button. Remove the cd from your cdrom drive and press Enter. This is Ubuntu' s boot loading screen. Type in your username and password you have chosen during the installation process. Congratulations! You have successfully installed Ubuntu 8.10 Intrepid Ibex! Welcome to the world of Linux!
