Virtualization don't work on my computer

[Thom_gamer]

Hey,

I recently try to install virtualbox on my new PC and I have a problem.
On my old computer, everything was working fine but now there is always a problem when I install an OS.

Here is the OS I have tested :
- Kali linux
- Ubuntu
- Debian

Here is my configuration :
CPU : AMD Ryzen 7 3700X
Motherboard : Gigabyte x570 Gaming X
RAM : 16Go ( 3600MHz )
GPU : NVIDIA GTX950 ( from my old computer, I will change it )

I have tested :
- Enable Virtualization in the bios ( SVM Mode Enabled )
- Disable Hyper-V
- Some other things found on internet like reinstall virtualbox, verify that there is enougth space on my disk....

When I install ubuntu for exemple, at a moment of the installation, the screen stay the same and I can't do anything.
When I install Kali, I can install the system but when I launch it, same problem as ubuntu, I see the loading screen but the OS don't launch.
But I don't see any error code, the screen is just locked ( the screen of the VM not the screen of Virtualbox )

Sorry if my english is bad I don't speak it very well.
Thanks for your feedback .

Please right-click the guest in the main Virtualbox window's guest list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don't find that text, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

Thank you for the quick response !

I found effectively "Attempting fall back to NEM", so I have followed the instructions on the link you sent me and it work !

I had already executed this command before : "bcdedit /set hypervisorlaunchtype off", but it didn't worked.

This command has worked for me :
DISM /Online /Disable-Feature:Microsoft-Hyper-V

And thank you for the help

Good bye
