Hello,

I explain to you my problem:

I need to create a virtual machine on Ubuntu / Debian / Fedora whatever.
I am on windows 10.
I create my machine, 4GB of ram, 90GB hard drive VDI / VDMK (I tried both), with the OS in x64 download directly through the manufacturer's website.
So I try with the three distribution.

The machine launches, I choose my distribution, the first page for the installation appears then big freeze on the virtual machine.
Nothing can be done, nothing works so need to close the machine.

I already uninstall and reinstall properly.

Sorry, for my bad english !

It seems that you have Hyper-V enabled. You can tell if this is true from the status bar where the "slow" icon (Image) shows. Look in the "Control Panel" » "Programs and Features" » "Turn Windows features on or off", and make sure that the none of the following are active:
  • Application Guard
  • Credential Guard
  • Device Guard
  • <any> * Guard
  • Containers
  • Hyper-V
  • Virtual Machine Platform
  • Windows Hypervisor Platform
  • Windows Sandbox
  • Windows Subsystem for Linux (WSL)
If VirtualBox is running without Hyper-V enabled, where proper, hardware virtualization is actually available, then the standard virtualization icon (Image) would show. Disable Hyper-V in your host and see what happens...

If that doesn't work, enter the following command:

    bcdedit /set hypervisorlaunchtype off
followed by a cold boot, i.e. shut down the computer, pull the power plug for 10", reboot.

Thank you, it was an accounting problem with "Device / Credential Guard"

I disabled HyperV + Virtualization Based Security
