Hi, 

My system is asking for BIOS password which I have no idea when have I set it. Is there any way to reset it or master password of some kind?

Please help! 

It also shows some random Password Hint. Please check the attached image for that.

Call Dell support by voice phone.  Upon verification of ownership, they'll unlock the system.
