After installing Hyper-V Integration Services on the next reboot the VM displays BSOD 0x0000007B

  • Article

Hi,

Recently, I had some customers with VMs they just P2V'ed, or even had them running already on Virtual Server or Hyper-V. Now, they installed the latest Integration Components that came with the R2 Release.

After the required reboot, the VM shows a Bluescreen 0x0000007B INACCESSIBLE_BOOT_DEVICE

 

During Debugging I found that the Storage Driver of the ICs require the Windows Driver Framework (WDF), which was not loaded in this case. So the Storage Driver fails to load.

Looking into the Registry of the VM, shows that the WDF Driver was already installed previously, but had the wrong Group relationship, so it is initialized too late.

So here’s how to fix this issue:

1. Boot the VM into LastKnownGood. Press F8 during boot.

2. Open the Registry and drill down to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wdf01000

3. There is a Group Value that should have the Value WdfLoadGroup. In my cases it was wrongly set to base. Change this to WdfLoadGroup

4. Then remove the Integration Components from Control Panel/Software.

5. Reboot the VM (now without ICs)

6. Install the ICs once again

Cheers

Robert

    Thanks, this saved me a ton of time.   It happens EVERY time we do a P2V for some reason.

    Does anybody know why P2V does not change base... to WdfLoadGroup?

    Thanks so much.  Didn't want to be here four more hours trying to re p2v and then have it fail again.

    You are a star. I thought my virtualisation effort was doomed when my blue screening started. Thanks for this.

    You are the MAN! I was having all kinds of difficulties with the blue screens at one of our company locations. The strange thing is that this is the first time I've run into these issues and have P2V'ed multiple machines at various locations. Thank You!

    VMM 2012 SP1 (rollup 2)  still suffers from this  when doing a P2V. Thankfully I was able to boot a rescue disk and edit the registry. Didn't have to uninstall anything, simply booted and it was fixed. Thanks!

    I had the same problem but Last Known Good wasn't working. Here's what I did on my Hyper-V Server 2012 (console only):

  1. Make sure you are in a PowerShell window (just type "powershell" at the command prompt).
  2. > Mount-VHD path to your vhd
  3. Figure out the letter it used to mount the VHD, usually the next available D, E, F, G, whatever.
  4. > regedit
  5. Select HKEY_USERS then File -> Load Hive.
  6. Browse your mounted VHD to C:WindowsSystem32Config and load the SYSTEM file.
  7. Follow Robert's great instructions on fixing this problem.
  8. Select you loaded hive. File -> Unload Hive and close Regedit.
  9. > Dismount-VHD path to your vhd.
  10. Boot your VM and enjoy! Thanks Robert!

    I'm just coming in from the future to let you know this is still helpful 4+ years later and that the US will lose back to back in the Olympics to Canada.

    This definitely was a time saver for me as well. Same scenario, Windows server 2003 to Hyper-V on a brand-new server 2012 host. So the problem still does exist with the IC installation as of this date. Thanks for the article!
