On HP PCs or laptops press the Esc key during startup, and then press F10 to enter BIOS setup. Using the arrow keys to navigate, go to System Configuration and then highlight "Virtualization Technology." Press Enter to get the options for the setting and select "Enabled." Press F10 to save and exit, and then select "Y" for Yes. The system should then restart.
On Dell PCs or laptops, press the F12 key while the startup screen is displayed. Then select "BIOS Setup." Using the arrow keys (or the mouse, if that works on your PC), find "Virtualization Support," and select the (+) symbol to the left. Select "Enable Intel Virtualization Technology," select "Apply" and then shut down the PC.
On a ThinkPad, press the blue ThinkVantage button during startup and press F1 to enter BIOS setup. (Be quick as it will continue booting if you don't provide an input.) On the "BIOS Setup Utility" screen the highlight will already be on "Config," so press Enter. Scroll down and select (press Enter) "CPU." Use the arrow keys to move down to "Intel Virtualization Technology" and press Enter. Press down once to select "Enabled" and then press Enter. BIOS will inform you that "Changes have been saved," so press Enter to select "Continue." And that's it. Press F10 to save and exit setup and select "Y" for Yes. The ThinkPad will then restart.
