About Linux - The Ubuntu Pocket Guide offers this option :
By downloading a virtual computer application, such as the free-ofcharge
VMware Player (www.vmware.com/products/player), you can
install Ubuntu so it runs within a program window on the
Windows desktop.
A virtual computer is effectively a complete computer recreated in
software. It offers an excellent way to trial Ubuntu, although the
limitations of the virtual computer software mean you won’t experience
Ubuntu to its full advantage (desktop visual effects won’t work, for
example). Additionally, you’ll need a powerful PC with over 1GB of
memory for optimal results.
