Intel Virtualization not working correctly?

[beinik6]

Hey,

I recently wanted to use my VirtualBox again, but as I wanted to start my VM, this error came up:

VT-x is not available (VERR_VMX_NO_VMX).


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


It means that VT-x is not enabled, but it actually should be and the VM did already work in the past.

So, i checked that Windows HYPER-V is disabled. I checked my UEFI and I did NOT find an option called VT-x but only VT-d, and its enabled.

Also the "intel diagnostics tool" says that VT-x is not supported by my cpu????
I have an I7 8700k and its DEFENETLY supported.

I would love to get some help, because nothing works here...

Fixed it, reset my UEFI.
