MultiBootUSB is a reliable program having the aim to install numerous live Linux distributions on a removable drive. The program can automate the installation of Linux distros while reading a Flash drive for boot operations. It provides the best way to install the Linux OS without needing complex setup. It is a portable application so you can run it without installation. It works with ISO files that the user can load using a dedicated dialog. Creating the live distros is a one-click process, but it will take some time. The conversion tasks use two third-party applications, 7-Zip for the ISO extraction and Syslinux for the MBR installation. However, these are included in the download package, so you don’t need to install them separately. The application lists the created distributions neatly inside the primary window, from where you can hide or remove them. If you want to test them, use the QEMU program encased in this application especially for this task.
