What would you choose between BIOS and UEFI?

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.

How do you start an operating system?

Intel-based (IA–32) startup

  1. Power-on self-test (POST)
  2. Detect the video card’s (chip’s) BIOS and execute its code to initialize the video hardware.
  3. Detect any other device BIOSes and invoke their initialize functions.
  4. Display the BIOS start-up screen.
  5. Perform a brief memory test (identify how much memory is in the system)

PCs are categorized as UEFI class 0, 1, 2, or 3. A class 0 machine is a legacy system with a legacy BIOS; i.e. not a UEFI system at all. A class 1 machine is a UEFI system that runs exclusively in Compatibility Support Module (CSM) mode. CSM is a specification for how UEFI firmware can emulate a legacy BIOS.
