You need to do exactly what it says. Virtualization support at the processor level is disabled.

Reboot.. very first thing after power on:

  1. Hit F10
  2. Setup -> Advanced -> System Options
  3. Virtualization Technology menu.
  4. Enable from there.

If for some reason, you are having trouble getting into the BIOS screen via F10, you can google "How to Enter the BIOS on a Windows 10 PC" or similar for how to do that. I find hitting the function key at startup easier.
