How to install Ubuntu Linux Step by Step Explained

This tutorial explains how to install Ubuntu Linux step by step in detail with examples. Installing Ubuntu Linux involves several steps. Understanding these steps is the essential requirement to perform an error free Ubuntu Linux installation. Learn each installation step and its options in detail.

In this tutorial, we will learn Ubuntu installation process from the first screen which user interact just after the booting system with Ubuntu installation disk or image.

First screen is divided in two panes; left pane and right pane. Left pane allows us to localize the language. Right pane allows us to try Ubuntu without installation or install Ubuntu in hard disk.

To install Ubuntu in hard disk, click Install Ubuntu option

install ubuntu

In next screen, we have to select whether we want to use third-party software or not.

Several add-on features are available to enhance the existing functionality of Ubuntu. Some of them are essential and recommended. If system is connected with internet, Ubuntu can download and install them for us.

Select the “Install third-party software for graphics and Wi-Fi hardware, MP3 and other media” and click Continue button.

Although it’s not recommended, but if you do not want to use the third-party software, keep this box unchecked and click Continue button.

Now installation wizard will scan all attached hard disks for existing operating system and partitions layout. If wizard finds any, it will list them in next screen along with partition options.

Wizard offers two partition schemes: -

  1. Erase disk and install Ubuntu: - In this option everything is handled by wizard itself. Wizard will create all necessary partitions automatically. This option has two sub-options: -
    1. Encrypt the new Ubuntu installation for security: - If this option is checked, wizard will encrypt the installation data with security key. To use this feature, we must have to type the security key in next step.
    2. Use LVM with the new Ubuntu installation: - If this option is selected, LVM partition scheme will be used instead of standard partition scheme. To learn what is LVM and how LVM is used in Linux see this tutorial.

Partition Meta data is stored in partition table. Before we create partitions, partition table must exist. If partition table does not exist, disk will display as a blank disk in next screen.

To create partition table, select the disk and click New Partition Table button

Click Continue to confirm the action

Once partition table is created, we have to create necessary partitions.

Although we can complete Ubuntu installation with single / (root) partition, but it is highly recommended to create at least following partitions

/ Main and compulsory partition of Linux. If no other partition is specified, entire Linux will be installed under this partition.
/boot This partition is used to store booting files.
/home This partition is used to store user data.
swap This partition is used as the part of RAM. It does not contain any user specific data.

Let’s create all recommended partitions step by step starting from / partition.

  • Select the free space
  • Click + (Add) button
  • Specify the size of partition
  • Select file system type
  • Select mount point
  • Click OK to save the partition information
