YUMI (Your Universal Multiboot Installer), is the successor to our MultibootISOs. It can be used to create a Multiboot Bootable USB Flash Drive containing multiple operating systems, antivirus utilities, disc cloning, diagnostic tools, and more. Contrary to MultiBootISOs which used grub to boot ISO files directly from USB, 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.
Aside from a few distributions, all files are stored within the Multiboot folder, making for a nicely organized Portable Multiboot USB Drive that can still be used for other storage purposes.
YUMI was originally intended to be used to store and run various "LIVE Linux" Operating Systems and tools from USB. Using YUMI to install Linux from USB to a Hard Drive works on many but not all distributions. (I'm working to address this). If you find a distribution where the install does not work, please let me know.
YUMI works much like Universal USB Installer, except it can be used to add more than one distribution to run Live from your Thumb Drive. USB Bootable Distributions can also be uninstalled using the same tool!
