When the BIOS was too complicated and a minefield for novice users, every tech company introduced the concept of UEFI - Unified Extensible Firmware Interface. UEFI is a PC firmware interface designed to replace the BIOS. UEFI replaced the BIOS with the goal of bringing hardware and software together in mind. It was a big change from the BIOS, better configuration design in UEFI, less chance of accidental changes or crashes, and most importantly, easy to use. It also eliminates the hassle of pressing a psychotic key after seeing the first screen of the logo, to enter the BIOS menu. This might be a big relief for some users. Before UEFI, you had to press different keys on different boot logo screens to access different settings in the BIOS menu. If you can imagine the hassle in that.
Windows 10 UEFI mainly has two features.
- Firmware configuration utility
- Firmware Boot Manager
Firmware configuration utility
This is the main UEFI utility, it can help you change various options and set different values, from boot order to boot timer etc. Windows has a built-in function to access this utility, but manufacturers generally use the Delete or F2 key to activate it.
Firmware Boot Manager
It is usually accessed by pressing Esc, Enter, or any function key while the machine is booting. Basically this helps you make changes… one-time changes to the boot options.
There are two ways to access UEFI in Windows 10
