In this guide we will be providing a easy set of instructions for installing Ubuntu 12.04 on your computer. This guide already assumes you have prepared your computer for Linux or alternatively have followed the guides for VMware or VirtualBox.
While an internet connection is not required it is recommended so Ubuntu can install some needed updates. If you are using a wireless connection you can configure the wireless using the network manager on the top right of the screen. Just select the network manager, select the wireless network you would like to connect to and then when asked enter the wireless key.
The Download updates while installing will go ahead and download any available updates while the system is being installed, this will save you some time later on.
The Install this third-party software option can be . selected if you would like to be able to play mp3 files on your computer. Please note that this installs non-free (free in terms of freedom) software so you may like to deselect this option if you would like a completely open-source system.
Once you have completed the selections you want on this screen click Continue.
This section allows you to allocate how much hard drive space you will like to give to Linux. In this example we will be allocating all of the drive space to Linux, however if you are dual booting with Windows (or some other OS) you will have the option of resizing Windows to make room for Linux or to install Linux on any free space currently available. Once you have selected the option appropriate for you click Continue.
This screen will display a summary on what will occur with regards to your hard drive configuration. You can make any changed to the configuration you like, such as selecting a different hard drive to install to.
If on the previous screen you chose to install side by side with Windows, you will also be presented with an option to resize the windows installation. You can change the Windows size to leave as much room for Linux as you need.
If you are happy with the details click Install Now.
In this screen you can select which type of keyboard you have. Change the selected keyboard here if Ubuntu has not selected the correct one. You can also test if you have selected the correct keyboard by using the test box. After selecting your keyboard press Continue.
This screen allows you to personalize your installation. First enter your name in the top text box, you will notice that both the username and the name of the computer are filled in automatically, however these can be changed to any name you wish. Also enter the password you would like to use (and enter it a second time for verification).
If you are not worried about the security of your system you can also select the Log in automatically option which will bypass the login prompt when the computer starts.
The Encrypt my home folder option may be selected if you would like to have your home folder encrypted. This is a useful option for systems which have sensitive information because if your computer is stolen the contents of your home folder will not be able to be read without your password. Please note that there is a small performance penalty when this option is selected.
After you have completed this section press Continue.
The installation of Ubuntu 12.04 will now commence. The rest of the process is automatic and will take about 10 minutes. After the installation is complete press the Restart Now button and your computer will restart. During this process your installation CD will be ejected from the drive, remove the disc from the drive and press enter to confirm you have done so.
Installation is almost complete but there is one very important step before being able to use Ubuntu and that is to install all the required security updates.
If you didn't select the “Log in automatically” option earlier, log into your computer with the username and password you selected. Next ensure that you have a working internet connection.
Soon you will see the Update Manage window load in the background. Click on the toolbar option that brings up the Update Manager. This program will ensure you are running the latest updates on your system. To begin the update process click on the Install Updates button. At this point you will be asked for you password, enter it and press Authenticate.
When this is complete you will be asked to restart your computer, do this to complete the update procedure.
Your Ubuntu 12.04 system is now fully installed and up to date. For further guides in configuring certain parts of Ubuntu please view our Ubuntu Guides section.
