I recommend http://multibootusb.org
I have tried multiboot as described on pendrivelinux.com: http://www.pendrivelinux.com/multiboot-create-a-multiboot-usb-from-linux/
and this utility is by far the most complete and functioning multiboot package that I could find... YUMI did not work for me and I desired to install several iso distros on one USB stick. Running the multiboot script to install the package went off without a hitch in Mint 12 (Lisa).
I very much support heltonbiker's suggestion and would like to see this package included within Linux Mint.
PenDriveLinux has several interesting alternatives ...
The major drawback with this idea is that, at present, Multiboot only runs on Windows OS.
@13thSlayer: I know Mint has this tool already, and that it is inherited from Ubuntu. The idea is exactely to replace this tool, since the suggested substitute seems to have many advantages and, afaik, any real disadvantage. And by the way Unetbootin is also a great tool! Thanks for commenting
Linux Mint offers a LiveUSB creation tool inside the system. As for creating it from Windows or another Linux system, please use unetbootin, see http://unetbootin.sf.net
