“There are various software available for creating and running virtual machine image. Microsoft’s Virtual PC, VMware, and Sun Microsystems’ VirtualBox to mention a few. Usually, there are several steps you would need to follow in order to create a virtual machine. These include creating a virtual hard disk and then installing the required operating system on the virtual hard disk.
Recently, Microsoft-owned Sysinternals released a utility that would be useful for easily creating a virtual machine image from your existing hard drive contents. This can be very useful if you have one of your computers at home or work set up for a particular task and you want to access all the same tools and software temporarily from your laptop.
The tool is aptly called Disk2vhd. Its a small download and doesn’t require installation. Just fire up the application with administrator rights and you are good to go. It will show you various hard disks and partitions on your computer. Select the one you would like turned into virtual hard disks, hit create and the applications goes about doing its thing.”
