TL;DR
A BIOS reset is the restoration of a computer's firmware settings to factory defaults, done through the setup menu's load-defaults option, by removing the motherboard's coin cell for a few minutes, or by shorting a clear-CMOS jumper. Technicians reach for it when a machine will not boot after failed updates, overclocking, or misconfigured settings such as wrong boot order, disabled ports, or bad memory profiles.
What it means
A BIOS reset is the restoration of a computer's firmware settings to factory defaults, done through the setup menu's load-defaults option, by removing the motherboard's coin cell for a few minutes, or by shorting a clear-CMOS jumper. Technicians reach for it when a machine will not boot after failed updates, overclocking, or misconfigured settings such as wrong boot order, disabled ports, or bad memory profiles. It erases custom settings including boot passwords on many boards, but never touches the operating system or files on the drive. On modern UEFI systems with Secure Start features, a related recovery may be needed if firmware corruption is deeper.
