Universal USB Installer simplifies creation of bootable USB drives

Universal USB Installer (UUI) is a free, open‑source program that lets users turn a USB flash drive into a bootable medium for a wide range of operating systems. The tool guides users through three steps—selecting a Linux distribution or Windows installer ISO, choosing and formatting the USB drive, and launching the installation—while supporting persistence, FAT32 formatting, and Secure Boot enrollment.

UUI supports dozens of Linux distros (Ubuntu, Linux Mint, Debian, Fedora, Kali, etc.) and Windows installers, and can also run security or diagnostic tools from the same portable media. Its simple interface makes it suitable for beginners and advanced users needing a reliable, quick method to create live or installation USBs.
