How to create a virtual hard drive

Ever wanted to try out a new operating system without having to erase your existing one? Then use a virtual hard drive to install it without risking your current operating system.
Difficulty: Moderate
Open command prompt and search for disk management. You should see this screen upon opening it.
Select a hard drive to use to hold the virtual hard drive. Then select Action in the title bar and choose Create VHD. It will lead you to this screen.
Click browse to choose a place to save your VHD as well as what to name it. You also select how big you want it. If you wanted to install Windows 8 onto it, 20 GB would be needed. You can also choose if you want it to inflate to full size right away, or slowly as you add stuff to it.
Now you should be looking at a screen like the one shown here. It would be better to choose the MBR option as opposed to the GPT one. The reason displayed onscreen is why. Then select Ok. Next thing to do is right-click on the unallocated space and select New Simple Volume...
It will lead you to this wizard screen. Accept the default on the following screen which asks you to select a range of space. On the screen after that choose what letter you want to assign to the drive.
