UEFIÂ (Unified Extensible Firmware Interface) is a standard firmware interface for PCs, designed to replace BIOS (basic input/output system). This standard was created by over 140 technology companies as part of the UEFI consortium, including Microsoft. It’s designed to improve software interoperability and address limitations of BIOS.
TheÂ Last BIOS timeÂ metric is the amount of time in seconds that the UEFI firmware spends identifying and initializing hardware devices and running a power-on self-test (POST) before it begins booting Windows 10 when you start the computer.

TheÂ Last BIOS timeÂ time will vary for each computer, but you can often tweak yourÂ UEFI firmwareÂ settings like below to help lower the time.
This tutorial will show you how to see theÂ last BIOS timeÂ for how many seconds it took your PC’s BIOS (UEFI Firmware) to finish initializing at startup before bootingÂ Windows 10.
