What YUMI is

YUMI creates multiboot USB drives that can hold operating systems, installers, rescue disks, antivirus tools, and diagnostics. It supports both UEFI and legacy BIOS systems, and supported Linux distributions can retain files, settings, and installed packages across reboots. ISO files can be added or removed without reformatting the entire drive. YUMI Py is a Python rewrite that runs natively on Windows and Linux; it can test installed images with portable QEMU and complete USB drives with VirtualBox. Its LAN Share feature streams an installed ISO to another device on the local network through a browser. That feature has no login or access code and is intended only for trusted networks. YUMI exFAT is described as free and open source, and supports persistent storage up to 40GB for supported distributions. YUMI is free. YUMI Py requires Windows 10 or 11 or a modern 64-bit Linux distribution, an exFAT-capable USB drive, and administrator or root privileges. Preparing a drive can erase existing data, so back up files first.
