To resolve this issue, all you need to do is to enable the VT setting on your system, and you’ll experience a significant boost in the running speed..

The procedure for running BIOS varies across platforms. Hence, depending on your system’s build, the procedure outlined herein might not work for you.

Follow the steps below to run BIOS on your system:

  1. Power off your PC and reboot it.
  2. On the boot menu, run BIOS by clicking the F2 button (or any of the F-keys, depending on your system).
  3. Go to Configuration and locate one of the following:
    • Virtualization
    • Intel Virtual Technology or
    • VT-x.
  4. Enable the virtual engine.
  5. Hit the F10 button to save changes.
