If virtualization is disabled, you need to access the [BIOS](/sthelper/troubleshooting/acces-bios-easily.md), and:

For <mark style="color:blue;">Intel</mark> CPUs:

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

For <mark style="color:red;">AMD</mark> CPUs:

1. Activate SVM in BIOS (Secure Virtual Machine/Virtualization Technology/VMX).
2. Activate IOMMU in BIOS. (Note: 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.
