I am not able to enable virtualization through BIOS as I am getting grey text there (for the virtualization option) and not able to click on the checkbox. Once earlier when I was using windows 7 I setted up pre boot security password for it using HP security manager which is enabled till now, I uninstalled hp security manager after some time but pre boot security was still working.
Now my laptop runs on windows 8.1 64 bit. Later I installed hp security manger for windows 8.1 64 bit, but there was no option to disable pre-boot security. As I don't want to go back to windows 7 again due to some reasons, please tell me how can I enable virtualization on my system. My processor is Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz model number HP probook 4530s.
Please let me know if you need any other information. I would be very thankful of you.
