Hello Dilip Gawand,
Error code 0x800f0831 When installing a Hyper-V role, it usually indicates that the system has detected that the current hardware or software environment does not meet the minimum requirements for installing Hyper-V. Here are some possible causes and steps to fix them:
- Check the hardware requirements: Make sure your server meets the hardware requirements to run Hyper-V, including CPU virtualization support (usually Intel's VT-x or AMD-V from AMD) and the relevant BIOS options enabled.
- Update the operating system: Make sure that your Windows Server 2016 has all the latest updates and patches installed, and sometimes some issues with installing Hyper-V have been resolved through updates.
- Disable security software: Temporarily disable your antivirus software or firewall, and then try reinstalling the Hyper-V role.
- Corrupted or missing operating system components: Run the DISM tool to repair the operating system image and restore it to a healthy state:
DISM.exe /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Once the repair is complete, restart the server and try to reinstall the Hyper-V role.
I hope you the information above is helpful.
Best Regards,
Yanhong Liu
