Make a Live Bootable USB Kubuntu with Persistence

Want to try a Live USB Kubuntu without installing it on your hard drive? A bootable USB lets you test it in live mode. With persistence enabled, you can save files, settings, and installed software for future sessions. This guide shows how to create a Kubuntu live USB using tools like YUMI, Etcher, and dd — on Windows, Linux, or macOS.

Kubuntu Live USB Overview

• Website: kubuntu.org
• Developed by: Canonical Ltd.
• Persistence: Supported

What Is Kubuntu?

Kubuntu is a user-friendly Linux distribution based on Ubuntu and built around the KDE Plasma desktop. It provides a polished interface and a suite of KDE applications such as Dolphin, Konsole, and KDE Connect.

Why Use a Live USB?

Live USBs are also useful for troubleshooting systems with damaged or unbootable operating systems. You can use them to recover files, test hardware compatibility, or browse privately without leaving a trace. For travelers or tech support professionals, a persistent Kubuntu USB can serve as a lightweight and portable Linux workstation on any compatible PC.

A Kubuntu Live USB lets you:

• Test the OS without installing it
• Troubleshoot systems
• Carry a portable desktop
• Save changes when using persistence

What You'll Need

• PC or Mac: Windows, Linux, or macOS
• USB Drive: 8GB minimum (16GB+ recommended for persistence)
• Kubuntu ISO: Download here
• Tool: YUMI, Etcher, or dd

Warning: All of these methods will erase your USB drive. Make sure to backup anything you want to keep before proceeding.

Create Kubuntu Bootable USB on Windows

Method 1: YUMI (Recommended for Persistence)

1. Download and launch YUMI.
2. Select your USB drive.
3. Choose "Kubuntu" from the distribution list.
4. Browse to your Kubuntu ISO.
5. Set a persistence file size (optional).
6. Click Create and follow on-screen prompts.
7. Reboot and boot from USB via BIOS/UEFI.

Method 2: dd for Windows (Advanced)

Warning: This method can overwrite your hard drives if misused.

1. Identify your USB disk with diskpart and list disk.
2. Run select disk X and clean (replace X).
3. Download dd.exe.
4. Write the ISO:

   dd if=path\to\kubuntu.iso of=\\.\PhysicalDriveX bs=4M

5. Safely eject the USB.

Create Kubuntu USB on Linux

Option 1: dd (Terminal)

1. Check device with lsblk.
2. Run:

   sudo dd if=kubuntu.iso of=/dev/sdX bs=4M status=progress conv=fdatasync

3. Finish with:

   sudo eject /dev/sdX

Option 2: Etcher (GUI)

1. Download balenaEtcher.
2. Select the ISO and target USB drive.
3. Click “Flash!” to begin.

Create a Kubuntu USB on macOS

Mac users can also create a bootable Kubuntu USB using the dd command via Terminal or a graphical tool like balenaEtcher.

Method 1: Use balenaEtcher

1. Download and install balenaEtcher.
2. Launch Etcher, select the Kubuntu ISO file, and choose your USB drive.
3. Click "Flash" to begin writing the image.

Method 2: Use Terminal (dd)

1. Download the Kubuntu ISO.
2. Insert USB and run:

   diskutil list

3. Unmount the USB:

   diskutil unmountDisk /dev/diskX

4. Write ISO to USB:

   sudo dd if=~/Downloads/kubuntu.iso of=/dev/rdiskX bs=4m

5. Once finished:

   diskutil eject /dev/diskX

Enable Persistence (Optional)

If not using YUMI, you can create persistence manually:

1. Mount the USB:

   sudo mount /dev/sdX1 /mnt/usb

2. Create file:

   sudo dd if=/dev/zero of=/mnt/usb/persistence.img bs=1M count=4096

3. Format it:

   sudo mkfs.ext4 /mnt/usb/persistence.img

4. Rename:

   sudo mv /mnt/usb/persistence.img /mnt/usb/casper-rw

5. Label it:

   sudo e2label /mnt/usb/casper-rw casper-rw

6. Unmount:

   sudo umount /mnt/usb

Install Kubuntu from USB Permanently
