Step-by-Step Guide

1. Check System Requirements

Before beginning the installation, ensure your computer meets the minimum requirements for Ubuntu:

• Processor: 2 GHz dual-core processor or better
• RAM: At least 4 GB (8 GB recommended for smoother performance)
• Storage: Minimum 25 GB of free hard drive space
• Internet: Optional but recommended for updates and downloading software
• USB Drive or DVD: For creating installation media

2. Download the Ubuntu ISO

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

3. Create Bootable Installation Media

Once the ISO file is downloaded, you need to create a bootable USB drive or DVD.

• Using USB Drive: Use tools like Rufus (Windows), balenaEtcher (cross-platform), or UNetbootin to create a bootable USB.
• Using DVD: Burn the ISO file to a DVD using disc burning software.

4. Prepare Your Computer

Before installing, back up important data. Restart your computer and enter the BIOS or UEFI settings (usually by pressing F2, F12, DEL, or ESC during startup). Change the boot order to boot from the USB drive or DVD first.

5. Boot from Installation Media

Insert the USB drive or DVD and restart. The computer should boot into the Ubuntu installer. You will see a welcome screen with options to try Ubuntu or install it.

6. Select Installation Language and Keyboard Layout

Choose your preferred language and keyboard layout. This step ensures that the installation process and system interface match your preferences.

7. Prepare Installation Type

You have several installation options:

• Erase disk and install Ubuntu: This will delete everything on the hard drive and install Ubuntu as the sole operating system.
• Install Ubuntu alongside existing OS: Allows dual booting with Windows or another OS.
• Something else: Manual partitioning for advanced users.

Select the option that suits your needs carefully.

8. Configure Partitions (Optional)

If you choose manual partitioning, create necessary partitions:

• Root (/): Main partition where Ubuntu is installed (minimum 15-20 GB)
• Swap: Space used as virtual memory (equal to RAM size or more)
• Home (/home): Stores user files and settings (optional but recommended)

9. Set Time Zone

Select your geographic location for accurate system time and updates.

10. Create User Account

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

11. Install Ubuntu

Review your choices and click Install Now. The installation process will begin, copying files and configuring the system. This may take several minutes.

12. Complete Installation and Reboot

After installation finishes, you will be prompted to remove the installation media and restart your computer. Upon reboot, Ubuntu should load, and you can log in with your new account.

Best Practices

Back Up Important Data

Always back up your files before starting the installation to prevent data loss, especially if you plan to erase the disk.

Keep Your System Updated

After installation, update your system using the Software Updater or via terminal commands (sudo apt update && sudo apt upgrade) to ensure security patches and bug fixes are applied.

Use LTS Versions for Stability

Long Term Support releases provide five years of updates and are recommended for production or daily use environments.

Partition Wisely

Separate the root and home partitions to protect personal data during future reinstallations.

Enable Firewall and Security Features

Ubuntu includes ufw (Uncomplicated Firewall) which can be enabled to enhance security.

Learn Basic Terminal Commands

Familiarize yourself with essential Linux commands to manage your system effectively.

Real Examples

Installing Ubuntu on a Windows Laptop (Dual Boot)

Many users prefer to keep Windows alongside Ubuntu to access both operating systems. The process involves shrinking the Windows partition using Disk Management, creating free space, and then installing Ubuntu alongside Windows. During installation, choose the Install Ubuntu alongside Windows option. After installation, a boot menu appears at startup, allowing you to select which OS to boot.

Installing Ubuntu on a New Desktop

For users building a new desktop, Ubuntu installation can be straightforward by dedicating the entire disk to Ubuntu. This approach simplifies partitioning and setup. After installation, users often install development tools and customize their environment for coding, gaming, or multimedia.

Installing Ubuntu on a Virtual Machine

Developers and testers frequently install Ubuntu inside virtual machines (using software like VirtualBox or VMware). This method allows running Ubuntu within another OS without repartitioning disks. The installation process is similar but uses virtual hardware.
