Is there a way to create a password so that it's required to be entered when your computer is booted up? I live an apartment at college with friends and we often mess with each other's computers in the name of fun, when they can't get around my screen saver password they just hit the reset button. In my BIOS I have the option for a supervisor password and a user password, I've entered in a user password but nothing has come up when I reboot. Do I have to enable the feature somewhere else in the BIOS? Thanks.
