VT-x is not available (VERR_VMX_NO_VMX) (BEEN TRYING TO FIX FOR WEEKS)

[synboxin]

I have been using VirtualBox for a while now. I have a few Linux boxes going and a Windows 10. Everything was fine. I went to start my Windows 10 and it wouldn't start. I tried my others. I got a ton of errors. I ended up removing them and uninstalling and reinstalling VirtualBox. Now the 64bit option is removed from my options. I can't start any in 32bit I get the error

VT-x is not available (VERR_VMX_NO_VMX).

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

I've tried every single thing I could find online. I'm so lost, and need to get this fixed as soon as possible for work related stuff.

Have you read the very informative I have a 64bit host, but can't install 64bit guests? In short, you need to make sure that VT-x is enabled in the BIOS and that nothing else has taken exclusive control over it.

So one of the problems with that is, I don't have the Hyper-V option in my Windows features. I also don't have anything related to DeviceGuard. To disable Hyper-V I have to use CMD commands, and I also tried a tool called HyperVSwitch (currently says HyperV is disabled but is still running, might need to reboot) Which I've rebooted 100 times. I checked running services and can't find anything Hyper-V related running. Now when I do CMD commands to disable it I get an error.

You're focusing solely on Hyper-V, but not a word about anything that might be using Hyper-V. Look at the list of software installed. And look at the article again. It could be an antivirus, a debugger, or something else. The one sure thing is: something is using VT-x. Not necessarily Hyper-V directly.

As far as I'm aware nothing is using it. Is there away I could check though just to be 100% sure?

There's not a program that's going to tell you "Hey, this is using VT-x". Something is using your VT-x though. We can't tell from here, we don't know what you have installed on your computer. I bet you that if you uninstall all the programs, or if you re-install Windows, the problem will go away.
