Others seem to be saying no, but you can get two Operating systems on a device without partition. You can use a virtual machine called VirtualBox. It's free and easy to use. If you don't know about it, I wrote an article on it before on: http://www.appsum.info/virtualbox.html
You can download it directly from there as well
Hope this helps
