Hyper-V launch aborted due to auto-launch being disabled in the registry.

Over the weekend, I spent some time rejigging the disk structure in my R&D Hyper-V server. I used StorageCraft ShadowProtect to backup the entire server as part of a regular backup process. I installed all the new disks into the server and then proceeded to restore all the partitions.  Because I was not moving it to new server hardware, I did not do a Hardware Independent Restore at all – just a restore and then a reboot as that was all that was needed.

When I restored the server, it booted just fine, but I found that the Hyper-V machines would not start.  Further digging into the situation showed the error below in the System Event Log


On Windows Server 2008 R2, there is normally a 100MB partition at the start of the 1st physical drive that contains the C: drive. This partition is used to store Boot Configuration Data (BCD) information as well as other critical files. As part of my ShadowProtect backup, I do not backup this partition at all as ShadowProtect cannot restore it.

I did some digging and found that Microsoft have some info on this error here and it tracks back to the fact that I no longer have the original 100MB boot partition with its original Boot Configuration Data information.  The BCDEdit command can be used to modify this information.

If you use the BCDEdit /enum command you can get a picture of what is in the Boot Configuration Data store as you can see below on this machine.


You will note there is no mention of HyperVisor.

To fix this use the following procedure

  1. Launch a Command Prompt with Administrative privileges
  2. Run the command bcdedit /set hypervisorlaunchtype auto
  3. Reboot – you will find the error is gone

After you’ve done that if you run the BCDEdit /enum command again you will see that you now have a HyperVisor section.


Hope this helps someone else caught in this situation.

    Thanks a ton! I restored my server on to new disks from backup and had tons of problems with the bootmgr and had to recreate all that boot stuff.

    This helped a bunch and worked like a charm thanks! It happened to me after mistakingly setting my active partition to another drive on my Hyper-V server then setting it back to C. That didn’t work right and the server wouldn’t boot. So i had to rebuild my BootMGR with a Windows 7 startup repair, that didn’t include the Hypervisor section. Ran this command from the dos prompt on my Hyper-V server and it rebooted and worked no problem.

    When I initially commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment
    is added I get several e-mails with the same comment.
    Is there any way you can remove people from that service?
    Thank you!
