Guide to Installing Ubuntu on VirtualBox

Setting up Ubuntu on a VirtualBox virtual machine is a straightforward process. This guide provides a step-by-step approach to installing Ubuntu on VirtualBox, from downloading the necessary files to configuring your virtual machine. Whether you’re a seasoned Linux user or just starting out, this tutorial will equip you with the knowledge to get your Ubuntu virtual machine up and running.

Downloading the Necessary Files

Before you begin, you need to download two crucial components: VirtualBox and the Ubuntu ISO file. Download the latest version of VirtualBox from the official Oracle website, ensuring you select the correct package for your operating system (Windows, macOS, or Linux). Next, head over to the official Ubuntu website and download the desired version of the Ubuntu desktop ISO. Consider downloading the LTS (Long Term Support) release for greater stability.

Downloading VirtualBox and Ubuntu ISO

Creating a New Virtual Machine in VirtualBox

Open VirtualBox and click on “New.” Give your virtual machine a descriptive name (e.g., “Ubuntu 22.04 LTS”). Select “Linux” as the type and “Ubuntu (64-bit)” as the version. Allocate at least 2GB of RAM (4GB or more is recommended for a smoother experience). Create a virtual hard disk with a minimum size of 20GB (dynamically allocated is recommended).

Configuring the Virtual Machine

Before starting the installation, configure a few settings. In the virtual machine’s settings, navigate to “Storage” and select the “Empty” optical drive. Click on the disc icon and choose “Choose a disk file…”. Select the Ubuntu ISO file you downloaded earlier.

Installing Ubuntu

Start the virtual machine. You will be prompted to select your preferred language and keyboard layout. Choose “Install Ubuntu.” Connect to the internet if you want to download updates during the installation process. Select “Erase disk and install Ubuntu” (this will only affect the virtual hard disk, not your actual hard drive). Choose your time zone and create your user account with a username and password.

Ubuntu Installation Process

Post-Installation Setup and Updates

Once the installation is complete, restart your virtual machine. Log in with the credentials you created during the installation. It’s crucial to update your system after installation. Open a terminal and type sudo apt update && sudo apt upgrade -y. This will ensure you have the latest software and security patches.

Conclusion

By following these steps, you’ve successfully installed Ubuntu on a VirtualBox virtual machine. This provides a safe and isolated environment for exploring Linux, experimenting with new software, or developing applications. Now you can leverage the power and flexibility of Ubuntu without affecting your primary operating system.
