Unified Extensible Firmware Interface (UEFI) is a specification for a software program that connects a computer’s firmware to its operating system (OS). UEFI is expected to eventually replace basic input/output system (BIOS) but is compatible with it.
What happens if I change UEFI firmware settings?
Warning: Changing the wrong firmware settings can prevent your computer from starting correctly. You should only access the motherboard firmware when you have an excellent reason.
Should I be using UEFI or BIOS?
In general, install Windows using the newer UEFI mode, as it includes more security features than the legacy BIOS mode. If you’re booting from a network that only supports BIOS, you’ll need to boot to legacy BIOS mode. After Windows is installed, the device boots automatically using the same mode it was installed with.
What is the difference between BIOS and UEFI firmware?
UEFI supports drive sizes upto 9 zettabytes, whereas BIOS only supports 2.2 terabytes. UEFI provides faster boot time. UEFI has discrete driver support, while BIOS has drive support stored in its ROM, so updating BIOS firmware is a bit difficult.
What happens if you dont see UEFI firmware settings?
Run Settings > Update & Security > Recovery and select Restart now under Advanced startup. From the next screen, select Troubleshoot > Advanced options > UEFI Firmware Settings > Restart to make changes.
