While Windows 7 comes with native support for mount VHD files there is one downside , all VHDs are unmount it every the system goes through a reboot. The shortcoming can be remedied with the help of a free third party tool called VHD Attach created by Josip Medved. You can download VHD attach from the following page http://www.jmedved.com/vhdattach/ This is a two step tutorial. First we’ll have to specify the VHD we need to be auto mounted , second the VHD will be mounted with a drive letter. Note: This post assumes you already installed the application.
Start the application and click on the highlighted icon found at the top of the right corner. Now click on the Add button. Browse to the directory where the VHD you wish to mount is located and double click on the VHD to selected. Click on the OK button to save the changes.
Now that you are back in the main menu click on the Open icon. Once again browse to the location where VHD is found and double click on it. VHD Attach will display relevant information about the VHD. Click on the Attach button found at the top. After this step the VHD becomes accessible from My Computer. If you click on the Tools button you can see that the VHD will be mounted on every start up, you can even change the drive letter if you like. You can close the window if you like, from now on the VHD will be automatically mounted every time Windows starts. And here is the VHD displayed as a local drive. Comments and questions are always welcomed.
