"We couldn't complete the features" When installing Hyper-V

Keith 6

I am attempting to install Hyper-V so that I can install WSL 2. The installation proceeds to 98% then fails with the message in the title of this thread.
I have enabled these settings in the BIOS:

Hyper-Threading [ALL]
Intel Virtualization Technology

I have disabled my Anti-Virus.
I have run these commands.

dism /online /cleanup-image /startcomponentcleanup
dism /online /cleanup-image /restorehealth

Systeminfo lists the Hyper-v requirements as met:

 - VM Monitor Mode Extensions: Yes
 - Virtualization Enabled In Firmware: Yes
 - Second Level Address Translation: Yes
 - Data Execution Prevention Available: Yes

Windows 10 Pro Dev build 21390.1

Hi,

Thanks for posting on our forum!

1) First make sure Virtual Box and VMware Workstation are not installed.

2) Run SFC /SCANNOW after running dism.exe /online /cleanup-image /restorehealth

3) Do a Windows 10 Repair Install from the Microsoft Media Creation Link. Use the second link , work through it and start with Keep Everything. See if Hyper-V works after that.

Repair Install link (Microsoft Media Creation Link):

https://www.microsoft.com/en-us/software-download/windows10

Windows 10 is running, so click on the Download button (not Upgrade Button, select Run. This will launch the Repair and proceed normally.

Thanks for your support!

Virtual Box was previously installed, but I uninstalled it prior to running the steps outlined in my initial post.

I've tried it with SFC/SCANNOW and the results are the same.

I had just installed the dev version of Windows 10 prior to attempt to install Hyper-V. It was a big install and seemed almost to be a complete re-install of Windows. Would Repair Install find anything in these circumstances (i.e. immediately after a clean install)?

I'd already tried it both ways prior to posting my message here. I'll add it to Feedback hub.
