HELP?!

so i was dicking around trying to reinstall windows 7 on my laptop and i was in the boot menu setting it to boot off of the flash drive then i thought it would be smart to put a "master password" or something of the sort, this password made it so every time on boot up it would flash a little blue menu and ask for a password but somehow it reset it so now when i try to login before i even get to the windows login it wont let me in i took my shit all apart and looked it up but its been 5 hours and im completely stumped the laptop im using is a samsung NP-N130 a few tutorials told me to find the CMOS JUMPER and switch it to the other 2 pins but my laptop doesnt have one and the same tutorials told me to find the little metal battery but it doesnt seem to have one of those either im completely stumped and i was wondering if any of you had a clue as to what i should do to reset the bootup/bios password.
