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.

Linux Live USB Creator
Formerly known as uSbuntu Live Creator, the project started in November 2008, just for fun at first. Then I realize that many people were interested in such a tool and so I started to be more serious about it’s development. LinuxLive USB Creator is released under GPL v3 License Terms which means you can do almost whatever you want with its source code.
