What you need?
YUMI

How to?

1. Plug in your drive. Open YUMI with administrative privileges.
2. Now hit "I agree" for the license agreement.
   
3. Now select your USB device from the drop down menu. In our case it was F and you can also select the format option if you don't remember the file system of you drive.
   
4.   Now select the Linux distribution from the drop down list which you want to install on the drive. If you have the ISO and the program is unable to automatically locate it you can manually go to the folder in which you have saved it. But if you don't have the ISO then you can check the box which says "download the ISO".
5.  Wait for it to do its thing. It will open the 7 zip or various other programs as per requirement so don't freak out.
   
6.  Now it will ask you "Would you like to add more ISO/Distro Now on F:?". Hit yes and do the steps 4 and 5 again. 
   
7. After you have installed all the distributions you want then you can click on finish.
   
8. Now plug the drive in any computer and use your operating system.

Note:- 

• You can only install a limited number of operating systems on a drive as each operating system has different size.
•  And if your system has a CD drive then you might need to change the boot sequence in the bios.
