system password vs administrator password in BIOS settings
I just received a new Dell laptop. In the BIOS menus, I'm able to set a "system password" but unable to set an "administrator password" (greyed out). What is the distinction between these two passwords in the BIOS.
1.System Password: This will be prompted before the system can boot up, and load the operating system.
2.Setup password: The system will prompt for this password only when you are trying to access the BIOS settings.
