I have a Inspiron 15R 5537 and i'm new to the BIOS whereas with my old Inspiron 17R i was used to it. As I  like to be on the move and take my laptop to college and so, I would like to add a password giving the user to enter a password to enter the BIOS. And so i did but ever time I start up my laptop it asks for a password which i do not want. I only want it to pop-up when you try to access the BIOS by press F2. Also could someone explain what Admin is and System is, in the BIOS? I would assume that Admin is user and System is supervisor? Please correct me if wrong. Thank you
