Earlier this month I wrote how you can mount a VHD using the command line utility DiskPart. This is an extremely useful utility, but sometimes you just want the simplicity of using the Windows GUI interface. Well, in Windows 7 the Disk Management MMC snap-in makes this a breeze.
The easiest way to load the snap-in is to open Computer Management by right-clicking on the “Computer” link in the Windows start menu and choosing “Manage”. This action will open a whole host of utilities you can use to manage your computer, but for this exercise you will only need to use the Disk Management link located in the left pane under Computer Management\Storage. Once you click on Disk Management it may take Windows a few seconds to find all of your storage devices and display them in the right pane.
Once the storage devices have loaded you can click on the Action menu at the top of the window. You now have the “Attach VHD” menu option. Simply click that option and select the VHD file you want to attach.
Detaching the file is a little more confusing. To detach it you have to navigate to the disk in the bottom pane of the Disk Management utility. The left most column in that pane is a series of buttons with the disk name shown. Right click on the disk name (e.g. Disk 2 in the image below) and select “Detach VHD”. Ensure you don’t check the delete checkbox, unless you don’t want any data on the VHD anymore.
