Ubuntu is composed of many software packages, the vast majority of which are distributed under a free software license. The only exceptions are some proprietary hardware drivers.The main license used is the GNU General Public License (GNU GPL) which, along with the GNU Lesser General Public License (GNU LGPL), explicitly declares that users are free to run, copy, distribute, study, change, develop and improve the software. On the other hand, there is also proprietary software available that can run on Ubuntu. Ubuntu focuses on usability, security and stability. The Ubiquity installer allows Ubuntu to be installed to the hard disk from within the Live CD environment, without the need for restarting the computer prior to installation. Ubuntu also emphasizes accessibility and internationalization to reach as many people as possible.

Installing Ubuntu 12.04 LTS.

Wednesday, March 27, 2013

Once you've put the image you downloaded onto a CD, DVD, or USB, you will need to shut down your computer. 

This may be a good time to print this page, or just read through and make notes.

Turn your computer back on, tapping F12 to select a boot device when your screen shows the name of the manufacturer. 

You can then use the arrow keys, finally hitting enter, to select either USB or Disc Drive.
Click Install

1. Click Install

Once Ubuntu has booted, you will be presented with a screen that looks like this.
Click Install Ubuntu to install. You can open the installer again later if you choose to try it out, but remember it will be far slower running from a Disc/USB than had you installed it, and nothing you do will actually be saved.

2. Check both Boxes

We recommend checking both boxes, but if you don't want to install all updates while installing, or don't want to play MP3 files (music), then you can leave the relevant box(es) unchecked.
If you don't have at least 4.5GB of available drive space, then you can't continue. If you're not plugged in, then plug in before continuing. If you're not connected to the internet, then you'll be prompted to connect when you click continue. You can do it now using the icon to the left of the sound menu to connect. Mine shows two arrows, as i'm plugged in, disconnected it looks different, and a little change again if using WiFi. You can continue without connecting, but you won't be able to get updates, or any language packs you may require.
Check both Boxes
Choose How to Install

3. Choose How to Install

Yours will probably look a little different to mine here. My hard drive doesn't have anything on it yet, so i can choose either to use the whole disk, or specify partitions manually (surprisingly easy stuff). Yours may have a slightly different first option, and one or two extra.
It may say Delete Windows and Install Ubuntu and Shrink Windows and Install Ubuntu Alongside.
Choosing to install alongside will mean you are presented with a menu with the option to choose which operating system with the arrow keys and enter every time you turn on your computer.

4. Confirm your Choice

After clicking continue, you may be presented with a confirmation screen, much like this, to confirm your choices.
Click Install Now to begin installing.
You'll be asked a few more questions in a second about where you are, what your name is, and how you want your computer set up. These are for time settings, user names, and home folders.
Confirm your Choice
Choose your Location

5. Choose your Location

Now you get to choose your location by dropping a pin on this nifty looking map. This is to select your timezone and apply any regional adjustments.

6. Choose your Keyboard Layout

This is probably the most technical step in the installation, made a lot simpler by the Detect Keyboard Layout. Just click that and follow the instructions on screen.
Choose your Keyboard Layout
Set a Username and Password

7. Set a Username and Password

Now you get to enter your name, the name you want your computer to be (not really important), your username (again, you won't see this much, but it can't have capitals or spaces, best leave as it is made from your real name), a password (if you want, then confirm it, and keep it strong), whether or not to log in automatically, and whether or not to encrypt your home folder (which is where documents, music, and video folder can be found, among others).
I would not recommend encrypting your home folder, as this usually complicates things for you as much as any potential trespassers. It can lead to complications with keyrings, forgotten passwords, and bad data recovery. Only use if it is company policy.

8. Sit Back and Relax

Sit back and enjoy a little slideshow about Ubuntu, all the free, full-version software you've got, and just how great it is to have installed Ubuntu 12.04 Precise Pangolin LTS.
You can rest easy in the knowledge that your computer is faster, safer, and simpler to use, now it's running a free open-source system.
