In previous versions, I might be able to remove Hyper-V through ServerManagerCmd.exe but this was apparently deprecated in 2012 (it seems it doesn't even exist) or dism /Online /disable-feature /featurename:hyper-v but it's telling me that it can't provide this service to Windows PE.

How do I accomplish the same thing within Server 2012? Is there a way to access powershell from the menu below? I try going to Command Prompt there and typing powershell but nothing. When I type sconfig to attempt to install powershell, it says that script doesn't exist.

EDIT: I'm trying to do this from the recovery command prompt when you start up in advanced startup. I cannot boot into the OS since enabling Hyper-V

I am constantly being returned to this screen pretty much no matter what I do (other than going to command prompt):

enter image description here

The difference is it says continue to Windows DataCenter instead of windows 8. I tried the suggestion here : Server 2012 Server Core powershell not installed

but i get the error "DISM does not support servicing windows pe with the /online option"

    That is not a duplicate. The other one is about removing the feature through the wizard or powershell. I am asking about command prompt (e.g. advanced startup/recovery, etc) – Sinaesthetic Sep 25 '14 at 06:53
  • Umm, have you tried booting in Safe Mode? – Michael Hampton Sep 25 '14 at 13:37
  • Yes. What's happening is the computer continues to boot into advanced boot options (the blue screen with options to restore, etc). No matter what I select, if I try to load the OS, it'll restart the computer. So for instance, if I set it to boot into safe mode, it'll restart the computer. If I choose to "continue to windows" it'll restart the computer. Everything just restarts and leads to the same place. – Sinaesthetic Sep 25 '14 at 22:38

Ok so I figured it out. Unfortunately it didn't solve my problem, but at least I got answer to the original question:

Most examples I've found on the web gave me this which didn't work:

DISM /Online /Disable-Feature:Microsoft-Hyper-V

Unfortunately, this won't work for PE. So instead of using the /Online option, you have to point it to an image. Here is the command I used to get it to finally run

DISM /Image:C:\ /Disable-Feature:Microsoft-Hyper-V

Unfortunately, I'm still stuck in the loop of being returned to this options screen no matter what I do. But I have that posted in a different thread.

  • Using Dism /Image:C:\ solved my problem. I have an Lenovo X395 with Ryzen 5 Pro 3500 CPU. After installing Hyper-V Hypervisor through the Windows Feature GUI, the notebook restarts to a black screen. I can press F8 to boot to Windows PE command prompt and use the Dism /Image to remove the Hypervisor feature. The next notebook restart brings me back to normal Windows 10. Thanks. – etoricky Dec 28 '20 at 08:20

I had this particular challenge and a search for the solution brought me here. However, this is the solution that worked great.

Open command line ( Run as Administrator )

Go to the base prompt ( C:\ )

Type:

bcdedit /set hypervisorlaunchtype off [Enter]

You should get a response "This operation completed successfully"

Restart the computer.

Your VMware should be able to run now with the machines as well.

I got this result on my Windows Server 2012R2
