So I have a Window Server 2008 machine that I need to restore. The machine is on, but will not boot into the OS.

I really don't need the machine anymore.

I have Windows Server Backup vhd files.

Is there anyway to create a bootable image from the vhd files? I have other servers that can connect to the machine, run HyperV, run Windows Server Backup, but if the server will not boot to the operating system I think I am screwed.

I have tried creating a VM in HyperV but when I set any of the .vhd files to the VM IDE, the virtual machine will not boot.

If I could extract an image from the Windows Server Backup .vhds than I can create a VM and solve my problem. But I get the impression I cannot do this with Windows Server Backup .vhds


I'm not 100% sure, But based on my own experiences, this should work: Here are the steps to follow:

Create a virtual machine in Hyper-V and attach the Windows Server Backup VHD file Boot the Hyper-V machine to WinPE

Launch Regedit

Highlight HKLM and click Load Hive

Depending on the configuration of the system partition, navigate to >C:\Windows\System32\config or D:\Windows\System32\config and load the SYSTEM hive Follow the registry changes listed below

HKLM/System/CurrentControlSet001/Services/ and then then modify the "Start" value according to the numbers listed below:

Aliide = 3

Amdide =3

Atapi = 0

Cmdide = 3

iaStorV = 3

intelide = 0

msahci = 3

pciide = 3

viaide = 3

Highlight HKLM and click Unload Hive Reboot and wait a minute or two

  • Do you know how I Boot the Hyper-V machine to WinPE? Not finding anything online that doesn't already assume you know what WinPE is and how to do it... – Brian Jan 16 '15 at 23:03
  • I don't think I can boot to WinPE unless the VM boots in the first place – Brian Jan 16 '15 at 23:11
  • You Might need a winPE disc from a good server image. (technet.microsoft.com/en-us/library/dd744530%28v=ws.10%29.aspx) try that – Gravy Jan 16 '15 at 23:41

    If you can't get PE set up easily, could you attach the VHD to an existing VM and edit the registry from that? – Celery Man Jan 17 '15 at 7:24
