Having a virtual machine on-hand can be useful for a variety of purposes, such as testing software or tweaks in a sandboxed environment that is separate from your primary operating system. A virtual machine can also help you to run older software that doesn't work with your new operating system, or simply exploring a new operating system altogether.
With the launch of Windows 8's Consumer Preview, you're probably itching to spend some quality time with Microsoft's latest operating system. Although you may have already downloaded the ISO, we bet some of you haven't decided how you're going to install it.
Running Windows 8 in a virtual machine won't remove your current OS, you can access it anytime you want without rebooting and it doesn't require any extra hardware. What's more, the test OS can be deleted in only a few mouse clicks.

We'll show you how to create a bootable USB flash drive with Chrome OS or run the it using a free virtual machine.
