UEFI is a more functional and more secure replacement to BIOS, despite the fact that its implementation in Windows 8 has been the subject of considerable controversy. You have the ability to restrict your computer so that it will only boot into authorized operating systems by using the Secure Boot function. However, there are still certain security flaws that might potentially impair UEFI’s operation.
Which is better, BIOS or UEFI?
In general, the more modern UEFI mode should be used to install Windows since it provides more security protections than the more traditional BIOS mode. You will need to boot into legacy BIOS mode if you are booting from a network that only supports BIOS. This is because the BIOS format is the only one supported by the network. After Windows has been installed, the system will automatically start up in the same mode as was used during the installation.
UEFI: Is it hackable?
In the wake of the recent discovery of UEFI spyware, cybercriminals now have the ability to immediately deploy hacking tools or malware to affected computers from the pre-boot environment.
