multiboot on usb?

[abdelkader belahcene <abelahcene@gmail.com>]

Hi,
I want to check different distros ( instead of using  several pens), so

I want to create on an usb pen  a mutli boot system.
I used  unetbootin, it works fine but  for only one system   at time.
on Windows there are some tools like YUMI, i tried it not working correctly,
then I want one working on linux system.

Any idea please
thanks a lot
regards
