How to Install Ubuntu Linux step by step tutorial

Step 1: Prerequisites

You'll need to the following before starting the installation:
  • Connect your system with power.
  • At least 25 GB HDD/2 GHz dual core processor/2GB RAM
  • Bootable DVD or a USB flash drive containing the version of Ubuntu you want to install.
  • Internet connection (if possible, not compulsory)
Step 2: Boot from USB flash drive

try holding F12 when your computer first starts. With most machines, this will allow you to select the USB device from a system-specific boot menu.
A few seconds later, after the desktop has loaded, you'll see the welcome window. From here, you can select your language from a list on the left and choose between either installing Ubuntu directly, or trying the desktop first (if you like what you see, you can also install Ubuntu from this mode also).

Step 3: Preparing to install Ubuntu
After choosing to install Ubuntu from the welcome window, you will be asked about updates and third-party software.
  • I advise enabling both Download Updates and Install third-party software.
  • connected to the internet so you can get the latest updates while you install Ubuntu.
  • If you are not connected to the internet, you will be asked to select a wireless network, if available. I advise you to connect during the installation so Ubuntu server can ensure your machine is up to date

Step 4: Installation Type

Use the check boxes to choose whether you'd like to Install Ubuntu alongside another operating system, delete your existing operating system and replace it with Ubuntu.

Step 5: Begin Installation

After configuring storage, click on the Install Now button. A small pane will appear with an overview of the storage options you've chosen, with the chance to go back if the details are incorrect.

Click Continue to fix those changes in place and start the installation process.

Step 6: Select Your location 

Type the name of a local town or city or use the map to select your location.

Step 7: Select Your preferred keyboard layout

To tell Ubuntu the layout of your keyboard, click on the language option you need followed by your keyboard's specific layout.

Keyboard layouts can always be changed, and supplementary layouts added, from the desktop after installation.

Step 8: Enter User Details

Enter your name and the installer will automatically suggest a computer name and username. These can easily be changed if you prefer. The computer name is how your computer will appear on the network, while your username will be your login and account name.

Next, enter a password. The installer will let you know if it's too weak password.

You can also choose to enable automatic login and home folder encryption. If your machine is portable, I recommend keeping automatic login disabled and enabling encryption. This should stop people accessing your personal files if the machine is lost or stolen.

Step 9: Installation Started

The installer will now complete in the background, installation time depending on the speed of your machine and network connection, this should only take a few minutes.

Step 10: Installation Finish

After everything has been installed and configured, a small window will appear asking you to restart your machine. Click on Restart Now button and remove either the DVD or USB flash drive when promoted.

Congratulations! You have successfully installed Ubuntu, It's time to start enjoying Ubuntu!
