Error with Oracle VM VirtualBox: VT-x is not available (VERR_VMX_NO_VMX)


I've recently installed Oracle VM VirtualBox on my Windows 10 computer, and I'm trying to make an Android Virtual Machine. The problem is that when I go to start the VM, it displays the following error:

VT-x is not available (VERR_VMX_NO_VMX).

Result Code:   
E_FAIL (0x80004005)  
IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I've already checked that my CPU is compatible with VT-x, and it's activated in the BIOS (In my case, I activated VT-d because there isn't an option for VT-x, but I've read that they're the same thing. If I'm wrong please correct me). I also have disabled Hiper-V, but it didnt' work.

Do you have any ideas on what's the cause of this problem?


I have a Gigabyte GA-H270M-DS3H motherboard with the F7 BIOS Version. I have an Intel I7 7700 (not K) CPU

Regarding this post, I've tried everything there, except for turning on VT-x on the BIOS, because I don't have the option, and because I thought that VT-d was the same thing. If not, how do I turn on VT-x?

What I did was turning off Core Isolation, specifically Memory integrity.

At first, I couldn't access this configuration, but, by changing the following registry key to 0, I could: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity\Enabled.
