On Wednesday, Microsoft officially released the Windows 8 Consumer Preview (which is essentially a fancy term for 'public beta'). If you're eager to dabble around with the build in a virtual machine - perhaps due to the lack of a non-production machine, a spare partition, the fear of using it in a production environment, or, well, if you just want to install it in a virtual machine - then you're in luck.
Whether you're eager to get the freshly released Windows 8 Consumer Preview installed but don't have DVDs at hand, or if you'd prefer to not use such an outdated method of installation, we'd recommend that you install by creating a bootable USB stick with the ISO. When the Windows 8 Developer Preview was released, we wrote an extensive guide covering just how to do this by using the Windows 7 USB/DVD Download Tool. So, to go about preparing the bootable USB step, follow the steps in the guide with the Consumer Preview ISO of your choice.
