What is UEFI?

How does UEFI work?

Advantages of UEFI

  • Was designed as an industrial standard so you can be sure that all platforms will be the same.
  • Enables users to handle drives that are larger than 2 TB, while the old legacy BIOS couldn’t handle large storage drives.
  • Computers who use UEFI firmware have faster booting process than the BIOS
  • Has a simpler graphical user interface and also has much richer setup menus than legacy BIOS.
  • Its modular structure makes it flexible and allows it to be adapted to special hardware environments and requirement profiles.
  • Can be extended with special functions and programs (e.g. digital rights management, games, web browsers, hardware monitoring, fan control)
  • Integrated boot manager which manages the various bootloaders for different operating systems
  • Early integration of drivers is possible (which then no longer needs to be loaded by the operating system)
  • A dedicated command line tool is available for performing diagnostics and troubleshooting (UEFI Shell)
  • Network functionality even without an active operating system
  • Supports networking function in the UEFI firmware itself, which helps remote troubleshooting and UEFI configuration and enables remote maintenance (remote upgrade of firmware components or the entire firmware) and booting via the network..
  • Increased security through the Secure Boot feature. This means that the validity of the operating system can be checked to ensure that no malware tampers with the startup process.
