Virtual PC problem in configuration

Hello guys and girls here,

I installed Windows Virtual PC along with Windows XP Mode on my computer having specs of Pentium core I 5 second generation processor with 4 GB RAM running Windows 7.

When I try to configure Windows XP Mode in Windows Virtual PC, following error messages appears.

Windows Virtual PC

Unable to Start Windows Virtual PC because

Hardware-assisted virtualization is disabled

Please follow these steps to enable hardware virtualization:

-Restart the computer and enter BIOS setup.

-Save BIOS setting.

– Power off the computer, wait for few seconds and start the computer.

You can check your computer manufacturer’s manual for details on BIOS settings.

I tried  to understand and what I got is to go to my bios setup on the pc power on and locate every menu of that, but I cant able to find that hardware virtualization stuff. Is this some sort of hardware add-on or what as my pc is the latest one. Kindly help me to locate, add, and install this hardware based virtualization support as I badly need to run different flavor of Linux and Windows on virtual PC.

Thanks.
