2.1. Windows users

We recommend using a dedicated tool Q4OS imager for Windows, please see An easy way to create Q4OS Live bootable USB forum topic for Imager description and download.

Windows Security Notice

We haven't signed the Imager installer yet, so you will need to satisfy Windows it's safe. On Windows 11/10, depending on the security policy of your system, a popup window titled "Windows protected your PC" may appear when trying to execute the installer.

You only need to click "More info" and confirm the Imager setup is safe to continue, then click "Run anyway" in the next dialog.

In the User Account Control (UAC) window, click Yes and the Imager setup window will now appear. Follow the instructions of the guide style installer.

2.2. Linux users

At first, download the desired ISO image from the downloads section of Q4OS website. As Q4OS is Debian based, please follow Debian instructions to create bootable media.

Command line method (dd)

For experienced users, you can use the dd command:

sudo dd if=q4os-5.8-x64.r1.iso of=/dev/sdX bs=4M status=progress && sync
Replace /dev/sdX with your USB device path. Use lsblk to identify the correct device.
