Whereas antiquated BIOS can take around 30 seconds before allowing an operating system to start, UEFI is said to boot in a fraction of that time
Those frustrating boot-up moments while we wait an absolute age for our computers to load up are set to get somewhat shorter with the impending retirement of system BIOS. Despite now being a very old technology and relatively stuck in its ways, the BIOS is still found in many modern machines. Instead of taking around 25 - 30 seconds before giving the all-clear for an operating system to start, a new kid on the block is well on its way to offering instant-on. It's not quite there yet, but the Unified Extensible Firmware Interface (UEFI) is getting closer.
