Windows 10: Severe boot problems with Hyper-V enabled

Hello, I always have boot problems on my Lenovo All-In-One when I activate Hyper-V. The problems most often occur with "Restart". Unfortunately, this also includes a restart after a Windows update. Problems are in order of increasing severity: 0. Sometimes the computer starts normally. No Trouble. 1. The computer takes 4 minutes to start up, the screen is black. without Hyper-V, the computer does not even need 10 seconds. 2. The computer takes up to 10 minutes to start, the screen is black during this time. 3. The computer does not start at all, but the LED on the power switch is on and

Can't Enable Hyper-V in Windows 10 Professional

Hi,



Thank you for writing to Microsoft Community Forums.



I appreciate your effort on this. As per my research the error code 0x800f0831 is generated when .Net Framework 3.5 is not enabled on the computer. I suggest you to try enabling .Net Framework 3.5 on the computer. Follow the steps mentioned below:

1. Press Windows key + R, to open
   Run dialog box.
   
2. Type appwiz.cpl and click on
   OK.
   
3. Click on Turn Windows features on or off.
   
4. Now, select the check box for .Net Framework 3.5 and click on
   OK.
   
5. Restart the computer.
   

You can also check if Virtualization feature is enabled in BIOS or not, if it is not enabled, I suggest you to enable it.

Enabling Hyper-V causes Windows 10 unable to boot

I'm having issues enabling Hyper-V in the "Add Windows Features" option in the control panel. I was hoping to increase performance with Google's Android Emulator for testing. Upon enabling Hyper-V, Windows
applies changes and resets. Windows is then unable to boot after this. Previously I had thought it may have been conflicting drivers from Virtualbox. After the last attempt, I was unable to use system restore or boot into Safe Mode and had to clean install.

I clean installed Windows 10 and installed windows updates and graphics / chipset drivers and tried to re-enable Hyper-V again. I also tried disabling "Fast Boot" in control panel at this time after reading
it may cause issues when enabling Hyper-V. I ran into the same problem but thankfully was able to boot into safe mode and windows successfully rolled back the feature and then booted normally.

I have the virtualization option enabled in BIOS. According to systeminfo, I have the requirements for Hyper-V AFAIK.

systeminfo command reads as follows:

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

OS and Hardware:

• Windows 10 Enterprise
• MSI x470 Gaming Plus
• Ryzen 3 2200g

Any help would be greatly appreciated. Let me know if any additional information is required.
