YUMI (Your Universal Multiboot Installer) is the successor to MultibootISOs. It is a really useful tool that lets you create a Multiboot USB Flash Drive that contains multiple operating systems, antivirus utilities, disc cloning tools an diagnostic tools.
Where YUMI differs from MultiBootISO's that use 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.
Apart from a few distributions, all the necessary files are stored within the Multiboot folder. This makes for a nicely organized Multiboot Drive, which can still be used for storing other data.
Added initial support for KaOS, VyOS, Bluestar Linux, Raspberry Pi Desktop, and XenialPup.
Medicat now extracts to the root folder until I find a fix for lost paths.
