For computer geeks or enthusiasts who want to understand how the underlying hardware works, so they can personalize the nitty-gritty of their personal computers. Here is the big question: Which one is better? UEFI or BIOS? And which one you should use? It’s a good question for anyone who wants to configure their computers to match their personal interests. Short answer: UEFI is newer, better and comes loaded on most modern PC. Although it is important to note that things are not as simple as black and white. Long answer: Here is an outline of the functionalities both UEFI and BIOS provide. A few years ago a major company in this field had announced its plans to completely replace it with UEFI on all their chipsets by 2020. It was also said BIOS would soon be dead. Essentially, what is UEFI, and how is it different from the BIOS we’re all familiar with? When you boot your PC before booting your operating system, UEFI and BIOS are low-level software that starts simultaneously. As opposed to BIOS, a more modern solution is the UEFI which supports larger hard drives, faster boot times, more security features, and—conveniently—graphics and mouse cursors.

Advantages of UEFI over BIOS

• ✎  UEFI supports secure startup, which means that the validity of the operating system can be checked to ensure that no malware tampers with the startup process.

• ✎  More than 4 primary partitions are supported by UEFI

• ✎  Drives larger than 2 TB can be handled by UEFI, which was not the case with BIOS.

• ✎  The UEFI firmware has a faster-boosting process.

• ✎  BIOS has a tad bit of a complicated graphical user interface in comparison with UEFI. Now, UEFI uses a much simpler interface and has much richer setup menus than legacy BIOS.

Due to these advantages or rather upgrades, UEFI is regarded as a successor to BIOS.
