After Windows is installed, the device boots automatically using the same mode it was installed with.

Is UEFI BIOS mode good?

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. UEFI offers security like “Secure Boot”, which prevents the computer from booting from unauthorized/unsigned applications.

UEFI can allow only authentic drivers and services to load at boot time, making sure that no malware can be loaded at computer startup.

What are advantages of the UEFI BIOS when compared with the legacy BIOS?

Benefits of UEFI boot mode over Legacy BIOS boot mode include: Support for hard drive partitions larger than 2 Tbytes. Support for more than four partitions on a drive. Fast booting.

Should I change UEFI firmware settings?
