HP Probook 4530s Admin BIOS password

I have a HP Probook 4530S. Whenever i go to BIOS i can see to options one is ADMIN BIOS (somthing like that) and the other one is my user name in my laptop. Now, i remember setting up the the second one in BIOS using my finger print (but at that time there were no ADMIN BIOS). I can get into the second on but whenever i click on the ADMIN BIOS it asks for a password. I dont even remember making this ADMIN BIOS how am i supposed to remember the password? However i tried all the possible passwords i cud use but none of them work.

Is there any default password? If so what is it? How can i remove this Admin Bios & make the other one the Admin
