Ubuntu is one of the most popular Linux distributions available today. Its ease of use, active community support, and regular LTS releases make it an ideal choice for Linux beginners and professionals alike.

Typically, installing Ubuntu requires downloading a large 2GB+ ISO installation image and writing it to a USB drive or DVD. However, Ubuntu also offers a mini ISO that is much smaller in size, making it handy for systems with limited bandwidth or storage.

In this guide, you'll learn:

  • What is the Ubuntu mini ISO and its advantages

  • How to download the latest mini ISO

  • Steps to install Ubuntu using the mini ISO

  • Tips for troubleshooting the installation process

Let's get started!

What is the Ubuntu Mini ISO?

The Ubuntu mini ISO is a small bootable image that contains just the bare essential components to start the Ubuntu installer.

Rather than packing all the files and packages for Ubuntu into one large ISO file, the mini ISO:

  • Is only around 100MB in size

  • Boots up a minimal Linux environment

  • Downloads necessary packages on demand during installation

This means you can install Ubuntu without needing much storage space or internet bandwidth upfront.

Some key advantages of using the mini ISO for installation include:

  • The small file size makes it easy to fit on old USB drives

  • Allows installation on systems with poor internet connections

  • Gives flexibility to choose which packages to install

  • Requires less data if you have a metered or capped internet plan

  • Quicker download time compared to the full 2GB+ ISOs

Overall, the mini ISO offers a lightweight and customizable Ubuntu installation experience.

Downloading the Latest Ubuntu Mini ISO

To get started, you'll first need to download the latest Ubuntu mini ISO image. Here are the steps:

  1. Go to the Ubuntu Releases page.

  2. Under "Ubuntu Installation Images", click on the link for the latest Ubuntu version's mini ISO.

    For example, for Ubuntu 22.04 it would be:

    ubuntu-22.04.1-live-server-amd64.iso

  3. Click the download link next to "Mini ISO" to save the file.

    The ISO will be around 100-200MB in size.

  4. After the download completes, you have the mini ISO image ready for installation.

Be sure to verify the mini ISO's checksum or GPG signature to confirm the file's integrity after downloading.

The mini ISO contains the minimal components needed to launch the installer and download the remaining packages over the internet. Next, let's walk through how to use it to install Ubuntu.

Installing Ubuntu with the Mini ISO

The installation process using the mini ISO is mostly the same as with the standard desktop ISO. Here are the steps:

1. Prepare Install Media

First, you need to write the mini ISO to a flash drive or DVD. Some options for creating bootable media:

  • USB - Use Etcher, Rufus, or dd Linux to write the ISO to a USB drive.

  • DVD - Burn the ISO file to a blank DVD using disk-burning software.

  • PXE Network Boot - Host the mini ISO on a PXE server to allow installation over the network.

Make sure to back up any important data on the target install media device first!

2. Boot the Mini ISO

Insert the prepared USB/DVD media and configure your PC to boot from it.

You may need to bring up a one-time boot menu at startup or change the boot order in your system's BIOS/UEFI settings.

The mini ISO will boot to a simple console-based installer with a grub> prompt.

3. Start Ubuntu Setup

At the grub> prompt, type:

install

and press Enter to load Ubuntu's installer.

If prompted to select an Ubuntu version, choose the latest LTS for stability.

The installer will begin initializing live environment components needed for the setup process. Be patient, this may take a few minutes.

4. Connect to the Internet

As the installer starts, it will prompt you to configure network connections to download additional components from Ubuntu repositories online.

For the mini ISO, an internet connection is required. Plug in an Ethernet cable if WiFi is unavailable.

Test connectivity using ping ubuntu.com. Ensure you get a response before proceeding.

5. Select Installation Options

Now you can customize Ubuntu's installation process:

  • Choose your language, location, and keyboard layout

  • Select normal vs minimal install, optional 3rd party software

  • Allocate disk partitions or configure LVM or ZFS

  • Set usernames and passwords

The mini ISO offers full flexibility here just like the standard installer.

6. Install Ubuntu!

With options configured, Ubuntu will install itself onto your hard drive.

Grab a coffee, as this may take 10-15 minutes depending on your internet speed and disk. The installer will fetch packages in the background.

Once done, reboot your PC and enjoy your fresh Ubuntu system!

The mini ISO provides a streamlined method to install Ubuntu without downloading multiple GBs upfront.

Troubleshooting Ubuntu Mini ISO Installs

The mini ISO has some key differences from full desktop ISOs that can cause issues. Here are some tips if you run into problems:

  • Try both Ethernet and WiFi - the mini ISO often lacks drivers to get WiFi working until after installation.

  • Verify internet connectivity - all packages are downloaded during installation, so you must be online.

  • Check disk space - ensure you have at least 10GB free for Ubuntu and swap space.

  • Try UEFI and legacy BIOS modes - some systems may only work with one boot method.

  • Test on multiple PCs - occasionally hardware compatibility issues may come up.

  • Validate ISO checksum - ensure your download is not corrupted.

  • Still stuck? The Ubuntu forums or Ask Ubuntu are great resources for troubleshooting.

The mini ISO may take some extra effort to work properly on some systems, but offers a handy minimal install option for Ubuntu.

Conclusion

While the standard desktop ISO works for most use cases, the Ubuntu mini ISO shines for systems with limited storage, bandwidth constraints, or custom installation needs. With just a 100MB download, you can install a fully-fledged Ubuntu system.

Follow the steps to download the latest mini ISO, create bootable installation media like a USB drive, boot the minimal environment, and install Ubuntu with optional customizations as needed.

In no time, you'll have Ubuntu up and running on your PC without the large upfront ISO download!

The mini ISO option makes experimenting with and installing Ubuntu more accessible. Give it a try on your systems and see the flexibility of this small but mighty installation image.
