UNetbootin

UNetbootin is a free, open-source program for creating bootable USB flash drives with Linux / BSD operating systems. The application supports dozens of the most common distributions and system utilities, each available in several versions.

You can choose to download the correct operating system, or if it already exists, you can specify the path to the ISO image. If you choose the second option, you can create a bootable flash drive even for a system that is not listed.

When selecting the desired distribution from the drop-down list at the top, UNetbootin shows its brief description, installation notes and a link to the project home page. Then you just need to choose the target drive and click on the OK button at the bottom of the program window. Downloading the distribution and writing it to a flash drive will begin.

UNetbootin allows users to create bootable USB drives for multiple Linux/BSD distributions, simplifying OS installation.

Not every distribution in the built-in list can always be downloaded (for example, Kaspersky Rescue Disk, which is based on the Linux kernel and is also included in the list), because download links change over time. In this case, download the distribution from its site by yourself, and then create a bootable flash drive using the ISO image.

In addition to all the advantages, the program has a fairly small file size and does not require installation on Windows. Besides USB drives, it offers a Hard Disk mode that adds a boot entry to the current system, and for Ubuntu it can reserve space to preserve files across reboots. UNetbootin is distributed under the GNU GPL and is also available for Linux and macOS.
