Traditionally, you would have to install different operating systems to separate partitions on your hard drive if you boot multiple OS platforms. The disadvantage is that malwares and viruses can spread among different partitions.
Another disadvantage is that it takes a considerable amount of time to create, delete or merge partitions when you need to. Since the advent of Windows 7, Microsoft has offered a new way to easily install and boot Windows from a Virtual Hard Disk (.vhd) file. This feature is even better in Windows 8.
What is a VHD file you ask? It’s a file format that emulates a real physical hard drive. It’s a hard drive within a hard drive—inception! In fact, you can even create and mount virtual hard drives within Windows 7 or 8 running from a VHD. I have yet to try an OS within an OS that runs from a virtual hard drive, but it’s possible with virtualization software like Virtual Box.
One of the benefits of a VHD compared to a physical partition is that it is a portable format. You can easily back up or restore it. Another benefit is security protection. If your other operating systems on the same hard drive get infected with malware, your OS on a VHD file will be isolated from that infection.
There are some minor disadvantages with running an OS from a VHD. Performance decreases about 3 percent, and you will lose the Hibernation and Bitlocker features. Moreover, only Windows 8 Pro/Enterprise and Windows 7 Ultimate/Enterprise support VHD booting.
Let’s create a VHD file so that you can install Windows 8 to it. You can do this during the install process, but it’s easier to demonstrate it using the tools available on Windows 7; that is, assuming you are running Windows 7. Step-by-step instructions are just ahead. Continue reading
There are now more than a handful of Start menu replicas out there for people that need their daily Start menu fix on their Windows 8 machines. From classic ones such as Classic Shell and StartMenu8 to experimental ones such as Pokki and RetroUI Pro. There are just no shortages of what type of Start menu one might need.
