Mount VHD file onto your filesystem

To mount a VHD file onto your file system, you either ran some very complicated VB (or PowerShell) Script or you used VHDMount.exe that came with Virtual Server. If you’re running Windows 7 (or Windows Server 2008 R2), you can now use Diskpart.

So, from an elevated command prompt, run Diskpart.

Select the VHD in question:

sel vdisk file=”c:\users\daven\desktop\xp professional.vhd”

Then attach it to your system:

attach vdisk

=============================================
Vanuit Hyper-V Manager kun je ook een VHD aan een andere VM koppelen, waardoor je bij de bestanden kunt komen.
