During installation on lenovo it set unknown password for bios

I've installed Ubuntu mate (2nd besides WW10) and after it I can't get access to bios - password is required.

Hi or Cześć :slight_smile:
Probably you have set it up during the installation of UM.
The step is asking for a password for "Secure Boot".
Probably you still remember what you have set up there :slight_smile:
