  1. Thanks very much for this. There’s not a lot of documentation around on this and it worked a treat! 🙂

  2. I tried this on a Windows Server 2008 R2 vmdk disk from using VirtualBox previously and the new VHD disk seems to have been formatted like it went through sysprep. Everything is gone. I must be missing something. Whats the point of converting the disk if you have to start over from scratch and rebuild everything?

    • Hello,

      can you explain me a bit more what you did? It sure looks like something went wrong.
      I haven’t experienced the same behavior.

      • Hi Gillou, I have a Win Server 2k8 R2 VM that is in VMDK format from when I used virtualbox. I used the vboxmanage clonehd command above to turn it into a VHD format so I can use it in Hyper-V on my Windows 8.1 desktop now. The command completed successfully and I was able to boot the new VHD machine in hyper-v. However, it was essentially sysprepped (renamed, had to reactivate, server roles removed, no data). How can I convert my VMDK to VHD without losing the system state/data on the VM? I tried 2Tware convert VHD but it would not even boot when I did it that way.

      • to be honest , I have no idea what is the problem in your case.
        I only tried to convert from vdi to vhd, maybe something about vmdk ?

  3. Michael contacted me directly to tell me that he solved the issue. here is the original message:

    “It turned out to be the way that VirtualBox handles snapshots. The newer versions use “branched snapshots”, which saves a separate disk file (.vmdk in my case) for each snapshot, that way you can revert back to any snapshot. I was converting the original disk file, which I thought contained everything. So when I converted the original disk, I was getting a sysprepped image, which is what I use for cloning those 2008 R2 servers! I deleted the snapshots which automatically incorporates those changes into the original disk. Then I converted the disk again following your steps in the article and Voila!”
