Geekers - Some time ago, we discussed a bit about BIOS and also how to find out the BIOS version without entering BIOS.


Maybe the word BIOS is familiar to you, but what about UEFI? UEFI (Unified Extensible Firmware Interface), in short, is a BIOS replacement. This firmware was first introduced by the Intel Boot Initiative, originally called EFI. Later, it was taken over by the Unified EFI Forum and named as UEFI.



UEFI comes with a Boot Manager so it doesn't require a separate Boot Loader and also provides decent startup and network speeds. Most of the latest laptops use UEFI with the Windows 8 operating system. Then how do you know if your laptop is using BIOS or UEFI? Come on, see the following explanation.
