Hello everyone!

I got a small problem and I am wondering if I could get some help here. I need a onetime password code to access my BIOS or find a password decoder so I can enter a generated code.

The problem happened when I tried to remove the BIOS pswd and I think I messed up something during the process. Now I can not log in since the pc does not accept the old password and now it is asking to enter a onetime password.  Can anyone help me out?
