How to Install Ubuntu: A Step-by-Step Guide

Ubuntu is one of the most popular Linux distributions, known for its user-friendly interface and robust performance. Whether you’re looking to replace your existing operating system, dual boot alongside another operating system, or simply experiment with a new environment, installing Ubuntu is a straightforward process. This guide will walk you through the installation step by step.

Step 1: Prepare Your System

1.1. Check System Requirements

Before you get started, make sure your hardware meets the following minimum requirements:

• Processor: 2 GHz dual-core processor
• RAM: 4 GB (8 GB recommended)
• Disk Space: 25 GB of free hard drive space
• Graphics: VGA capable of 1024×768 screen resolution

1.2. Backup Your Data

If you’re replacing your existing OS or partitioning your hard drive, it’s wise to back up your data to avoid potential loss during the installation process.

1.3. Create a Bootable USB Drive

1. Download the Ubuntu ISO: Head to the official Ubuntu website to download the latest version of Ubuntu.
2. Create the Bootable USB Drive:
   • Windows: Use tools like Rufus or balenaEtcher.
   • macOS: Use the built-in Disk Utility or balenaEtcher.
   • Linux: Use the dd command or tools like UNetbootin.

1.4. Change Boot Order

Insert the bootable USB into your computer and restart it. Enter your BIOS/UEFI setup (usually by pressing F2, F10, F12, or Del during startup) and set USB as the first boot option.

Step 2: Start Ubuntu Installation

2.1. Boot from USB

After setting the boot order, save the changes and exit. Your computer should boot from the USB drive, and you’ll see the Ubuntu welcome screen.

2.2. Choose Installation Type

• Try Ubuntu without installing: This option lets you try out Ubuntu without making changes to your computer.
• Install Ubuntu: Select this option to proceed with the installation.

Step 3: Installation Wizard

3.1. Language and Keyboard Layout

Choose your preferred language and keyboard layout. Click “Continue” to proceed.

3.2. Updates and Other Software

You will see options to download updates during installation and install third-party software (like graphics drivers and media codecs). It’s generally advisable to select both options.

3.3. Installation Type

You have several choices:

• Erase disk and install Ubuntu: This option will remove all existing data and install Ubuntu.
• Install Ubuntu alongside [Your Existing OS]: This allows you to keep your current operating system and dual boot with Ubuntu.
• Something else: This option lets you manually partition your hard drive.

Select the option that suits your needs and click “Continue.”

3.4. Disk Partitioning

If you selected “Something else,” you’ll need to allocate space for Ubuntu. Here’s how you can partition:

• Create a new partition for the root file system (/) where Ubuntu will be installed.
• You might also want to create separate partitions for /home (user files) and swap (for virtual memory).
• Click “Install Now” after creating partitions.

3.5. Time Zone

Select your time zone and click “Continue.”

3.6. Create User Account

Fill in your name, a computer name, username, and password. You can choose to log in automatically or require a password. Click “Continue.”

Step 4: Complete Installation

The installation process will now begin. It can take anywhere from a few minutes to an hour, depending on your hardware and selection options. Once the installation is complete, you’ll be prompted to restart your computer.

Step 5: Post-Installation

5.1. Remove USB Drive

When prompted, remove the USB drive to avoid booting from it again and capitalize on the changes you’ve made.

5.2. Log In to Ubuntu

After the restart, you’ll be greeted with the Ubuntu login screen. Enter your password, and you’ll be taken to your new desktop environment.

5.3. Update System

Upon logging in, it’s a good idea to open the terminal (Ctrl + Alt + T) and run the following commands to ensure your system is up to date:

sudo apt update
sudo apt upgrade
