Rufus formats USB drives and creates bootable USB sticks from ISO images, with BIOS/UEFI options and MS-DOS/FreeDOS support. Users appreciate its straightforward approach, though some seek alternatives that handle multiple ISOs or offer cross-platform compatibility.
Ventoy leads as the top-ranked alternative, allowing users to boot multiple ISO files from one USB without repeatedly reformatting - just copy new ISOs onto the drive. balenaEtcher appeals to users wanting a simple interface with verification steps, though some report struggles with Windows ISO boot disks. UNetbootin ranks highly as an open-source option with Windows, Mac, and Linux versions.
For specialized workflows, Popsicle can write one ISO image to multiple USB devices simultaneously with a simple click-driven workflow. These Rufus alternatives range from multiboot managers to straightforward image flashers, giving users flexibility in their bootable media creation approach.
Open source options dominate the bootable USB space, with YUMI exFAT, WinDiskWriter, and WoeUSB all offering transparent, community-built tools. Linux users have native support through YUMI exFAT and WinDiskWriter, while WoeUSB focuses specifically on creating Windows installer USBs from Linux systems.
For portable workflows, YUMI exFAT, WinDiskWriter, and dd can run from USB without installation - perfect for technicians who need tools on the go. Users seeking ad-free experiences will find clean interfaces in YUMI exFAT, WoeUSB, and dd without promotional distractions. The command-line tool dd provides the most minimal approach for advanced users who prefer direct ISO writing without graphical interfaces.
I have over 20 ISOs on one flash drive because of this utility. It's my favorite software for multiboot USBs. Keep in mind, however, that it doesn't work on any Mac hardware.
