Step-by-Step Guide

1. Prepare Your System

Before installing Ubuntu, ensure your hardware meets the minimum requirements:

• Processor: 2 GHz dual-core processor or better
• Memory: At least 4 GB of RAM
• Storage: Minimum 25 GB of free disk space
• Internet connection: Recommended for downloading updates and drivers
• USB drive or DVD: For creating the Ubuntu installation media

Back up any important data on your computer, especially if you plan to overwrite an existing operating system or modify partitions.

2. Download Ubuntu ISO

Visit the official Ubuntu website (https://ubuntu.com/download) and download the latest LTS (Long Term Support) version. LTS releases receive updates and support for five years, making them ideal for stability and security.

3. Create Bootable Installation Media

Use a USB flash drive or a DVD to create bootable installation media. For USB drives, tools like Rufus (Windows), Etcher (cross-platform), or UNetbootin are recommended.

• Insert the USB drive (4 GB or larger)
• Open your chosen tool and select the downloaded Ubuntu ISO file
• Choose the USB drive as the target device
• Start the creation process and wait until it completes

4. Configure BIOS/UEFI Settings

Restart your computer and enter the BIOS/UEFI setup (usually by pressing F2, Del, or Esc during boot). Make the following adjustments:

• Set the USB drive or DVD as the primary boot device
• Disable Secure Boot if necessary (some systems require this for Ubuntu installation)
• Enable Legacy Boot mode if your system doesn’t support UEFI boot

5. Boot from Installation Media

Save your BIOS/UEFI changes and reboot. Your system should boot into the Ubuntu installer. If it doesn’t, recheck your boot order and try again.

6. Start the Installation Process

Once the Ubuntu installer loads, you will see the option to “Try Ubuntu” or “Install Ubuntu.” The “Try Ubuntu” option allows you to test the OS without making changes to your system. Select “Install Ubuntu” to proceed.

7. Choose Installation Language and Keyboard Layout

Select your preferred language and keyboard layout. This step ensures the installer and system match your preferences.

8. Prepare Installation Type

The installer gives several options for partitioning and installation:

• Erase disk and install Ubuntu: Deletes all data and installs Ubuntu on your entire drive
• Install Ubuntu alongside existing OS: Sets up dual boot with your current operating system
• Something else: Manual partitioning for advanced users

Choose the option that fits your needs. For beginners, “Erase disk and install Ubuntu” is the simplest choice, but ensure you have backed up all your data.

9. Configure Disk Partitions (Optional)

If you select “Something else,” you can create and edit partitions manually. A typical setup includes:

• Root partition (/): Minimum 20 GB formatted as ext4
• Swap partition: Equivalent to your RAM size (optional if you use a swap file)
• Home partition (/home): For user files and settings (optional)

10. Set Time Zone

Select your geographical location to configure the system clock correctly.

11. Create User Account

Enter your name, computer name, username, and password. This account will have administrative privileges via sudo.

12. Installation and Setup

The installer will copy files and configure your system. This process can take 10 to 30 minutes depending on your hardware.

13. Restart and Remove Installation Media

After installation completes, the system prompts to restart. Remove the USB drive or DVD to boot into your new Ubuntu system.

14. Post-Installation Setup

Upon first login:

• Update your system with sudo apt update && sudo apt upgrade
• Install additional drivers if prompted
• Configure your preferences and software

Best Practices

1. Backup Important Data

Always back up your files before installing or modifying your system to avoid accidental data loss.

2. Use the Latest LTS Version

Long Term Support versions provide stability and long-term updates, making them ideal for production environments.

3. Check Hardware Compatibility

Review Ubuntu’s hardware compatibility lists or forums to ensure your hardware is supported, especially for printers, graphics cards, and Wi-Fi adapters.

4. Create a Live USB for Testing

Use the “Try Ubuntu” option from the live USB to test hardware compatibility before installation.

5. Partition Thoughtfully

Plan your partitions based on your usage. Separating /home from / helps preserve files during system upgrades or reinstallations.

6. Enable Automatic Updates

Keep your system secure and up-to-date by enabling automatic updates in the Ubuntu Software & Updates settings.

7. Use Strong Passwords

Choose a secure password for your user account to protect your system from unauthorized access.

Real Examples

Example 1: Installing Ubuntu on a New Laptop

A user purchased a new laptop without an operating system. They downloaded Ubuntu Desktop LTS ISO, created a bootable USB using Rufus, and installed Ubuntu by erasing the disk. Post-installation, they configured Wi-Fi, installed software like LibreOffice and Firefox, and enabled automatic updates. The laptop now runs smoothly with Ubuntu as the primary OS.

Example 2: Dual Boot Setup with Windows

An IT professional wanted to keep Windows 10 on their machine but also run Ubuntu for development. They shrank the Windows partition using Disk Management and created a bootable USB for Ubuntu. Selecting “Install alongside Windows” during setup, Ubuntu installed without overwriting Windows. The user now chooses the OS at boot time using the GRUB bootloader.

Example 3: Server Installation

A small business set up an Ubuntu Server on an old desktop. Using the Ubuntu Server ISO, they installed a minimal version without a graphical interface, configured SSH access, and set up web and database servers. This lightweight setup enhanced performance and security for their internal applications.
