VHD (Virtual Hard Disk) is the type of the file which represents a virtual hard drive (HDD). It has all those features which we find on our normal hard drive. It includes features like disk partitions & file systems, which consists of files and folders. This format was created by Connectix, later was modified by Microsoft, for what is now known as Microsoft virtual machine. A Virtual Hard Disk (VHD) allows multiple operating systems to reside on a single host machine. Creating VHD helps us in securing the data on our hard disk.

Step1. This process creates virtual disks in the .VHD format where the minimum size is 3MB. To begin, Right-click on My Computer and select to Manage. Alternately, you can type diskmgmt.msc into the Start search box and enter.

Step3.Browse to the directory you want the disk to reside, choose the size you want it to be, and select dynamic or a fixed. If you want the disk to expand in size as you add files to it, then pick dynamically expanding. Check Fixed size if you want a specific size and for it to stay that way.
