Dell Latitude E6420 XFR bios password issue

[mshiwpal]

Hey guys,
While trying to do a firmware upgrade on my Dell E6420 XFR and I'm getting "Please enter the admin password to process with the flash:" message. Now keep in mind I have no idea I had a password on the bios so I rebooted and went to see what's going on. I was able to get in but all options were greyed out and there's an Unlock button(see attachment). When I clicked the Unlock button, it says there's an administrative password. Can some one point me in the right direction on how to clear this? I don't remember putting a password on the laptop so i'm not sure if trying to update the bios caused this or what happened. Any help would be appreciated.

Thanks, in advanced.
