If you just try a different operating system without having to complete the current installation on your PC affect?
A first approach is initially on a USB drive or from a LiveCD (eg to boot Linux with Knoppix and Ubuntu ) in the existing hardware. The actual operating system on the PC will not start and remains unaffected. BartPE is conceivable in the Windows area, but rather only in popular support.
goes one step further virtualization software such as Virtual Box of Sun Microsystems. Here you can boot the new operating system to use in a window in your current operating system. The hardware is tricked into the operating system and the actual hardware resources are shared. Thus, it is also possible complete virtual test networks in building their own PC or globally, ie in client & Server role, buy into the existing network. Also VMWare is used. However, I consider the possibilities for action at the training or home users with more extensive VirtualBox.
in training and education company, I see many opportunities in virtualization technology as by the multiple use of hardware and the development of network scenarios.
