If virtualization is disabled, you need to access the BIOS, and:

For Intel CPUs:

-   Activate `VT-X` in BIOS. (Virtualization Technology/VMX)
    
-   Activate `VT-D` in BIOS.
    

For AMD CPUs:

-   Activate `SVM` in BIOS. (Secure Virtual Machine/Virtualization Technology/VMX)
    
-   Activate `IOMMU` in BIOS. (IOMMU/VT-D may appear as I/O Virtualization)
    

If you cannot locate these settings in your BIOS, be sure to enable advanced mode (F7,F2 or F12). It's also possible that your BIOS firmware needs updating. Please proceed with updating it.
