Linux is a powerful, safe, and adaptable operating system widely used by developers, IT experts, and common users seeking greater control over their systems. However, before you can enjoy its benefits, you must install it on your computer.

Fortunately, installing Linux is easier than ever. Modern Linux distributions have straightforward, user-friendly installers that walk you through the process step by step. However, before you begin the installation process, you must first create a bootable USB device.

A bootable USB stick enables you to install Linux on your computer or operate it as a live environment without causing any permanent changes to your system. What is the best part? Creating one is easy, and you do not need to be a tech expert to do it.

This guide will walk you through the entire procedure of how to install Linux on a flash drive, allowing you to effortlessly generate a bootable USB and install Linux on your PC.

What do you need to create a Bootable Linux USB?

Before we begin the process, make sure you have the following:

A computer with a USB port – This is the system where you will make the bootable drive.

A USB flash drive (at least 16GB) – A larger USB drive (32GB or more) is much preferable, especially if you want to use it as a portable Linux system.

A Linux ISO file – This is the installation file for the Linux distribution that you want to install. Popular choices include:

• Ubuntu (ideal for beginners)
• Fedora (is perfect for developers)
• Linux Mint (Windows-like interface)
• Debian (Stable and Reliable)
• Arch Linux (for Advanced Users)

A tool to create the bootable USB – There are multiple tools available for this, but some of the most reliable ones are:

• Rufus (Windows)
• Etcher (Linux, Mac, Windows)
• Ventoy (supports numerous ISOs on a single USB)
• Fedora Media Writer (For Fedora Installations)
• UNetbootin (cross-platform, simple to use)

For this article, we’ll use UNetbootin, which is compatible with Linux, Windows, and MacOS.

Step 1: Download and Install UNetbootin

If you are using Windows or macOS, follow these steps:

1. Visit the official UNetbootin website.
2. Download the most recent version for your operating system.
3. Run the downloaded file to install the software.

If you’re using Linux (Ubuntu-based systems), open a terminal and type these commands:

This will install UNetbootin on your PC, allowing you to generate a bootable USB.

Step 2: Insert Your USB Drive

Now that UNetbootin is installed, plug your USB flash drive into your computer.

Important Notes:

Backup your data: Everything on the USB drive will be wiped during this operation.

Check the USB drive name. On Linux, use the command lsblk to list all connected devices.

Step 3: Open UNetbootin and Select Your Linux Distribution

1. Launch UNetbootin from the Applications menu.
2. In the main window, select one of the following.
   • Choose a distribution from the list if you want UNetbootin to download the ISO.
   • If you have downloaded the Linux installation file, use an existing ISO.
3. If you selected a distribution, select the most recent version from the “Version” selection.

Step 4: Choose the USB Drive

1. Select USB Drive from the “Type” menu.
2. Select the correct USB disc from the “Drive” selection menu.

How to Make Sure You Select the Correct Drive:

• If you are using Windows, go to Disc Management and check the USB drive letter.
• If you’re running Linux, type lsblk in the terminal to get a list of drives.

Tip: To avoid picking the incorrect drive, remove all other external storage devices before proceeding.

Step 5: Create the Bootable USB Drive

1. Click OK to begin the process.
2. Unetbootin will:
   • Download the required files (if needed).
   • Extract and copy to the USB.
   • Install a bootloader so that your USB can boot properly.
   • Finalize the process.

Time required: It usually takes 5 to 15 minutes, depending on your system and USB speed.

If UNetbootin looks to get stuck at “Extracting and Copying Files,” do not panic; it will ultimately finish.

Step 6: Safely Remove Your USB Drive

Once the process is complete:

• Click Exit in UNetbootin.
• Take your USB drive out of your computer safely.
• Your bootable Linux USB is now ready! 

Step 7: Boot from the USB Drive and Install Linux

Now that your bootable USB is ready, you can learn how to install Linux on a flash drive and enjoy your new system!

1. Insert the USB drive into the computer where you intend to install Linux.
2. Restart the computer and navigate to the BIOS or boot menu (typically by pressing F2, F12, DEL, or ESC at startup).
3. Select your USB drive to be the boot device.
4. The Linux installer will run; simply follow the on-screen directions to complete the installation.

That’s it! You now have Linux running on your machine.

Conclusion

Tools such as UNetbootin, Rufus, and Etcher make it easier than ever to create a bootable Linux USB drive. Whether you want to install Linux as your primary operating system or learn how to install Linux on a flash drive for live testing, this method provides a simple and fast solution.
