YUMI (Your Universal Multiboot Installer) can be used to create a multi-boot USB flash drive containing multiple operating systems, antivirus utilities, disc cloning, diagnostic tools and more. Aside from a few distributions, all files are stored within the Multiboot folder, making for a nicely organized Multiboot Drive that can still be used for other storage purposes. YUMI uses syslinux to boot extracted distributions stored on the USB device and reverts to using grub to Boot Multiple ISO files from USB, if necessary.

YUMI works much like Universal USB Installer, except it can be used to install more than one distribution to run from your USB. Distributions can also be uninstalled.

Note: YUMI v2.x can't remove distributions previously installed with Legacy YUMI! Although no longer supported, you can still Download Legacy YUMI.
