Spec score 7.4 #28 of 38 in Bootable USB Software

What it is

YUMI creates multiboot USB drives that can contain multiple operating systems, installers, rescue disks, antivirus tools, and diagnostics. It supports UEFI and legacy BIOS systems. Supported Linux distributions can preserve files, settings, and installed packages across reboots, and 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, test complete USB drives with VirtualBox, and stream an installed ISO to another device on a local network through a browser. That LAN Share feature has no login or access code and is intended only for trusted networks. 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 the maker instructs users to back up files first. YUMI exFAT is described as free and open source, with source code included in released versions; it supports persistent storage up to 40GB for supported distributions. YUMI is free and supports Windows and Linux.
