Advantages of UEFI

A computer firmware and operating system are connected by a software program called Unified extensible firmware interface(UEFI), Which is a specification(OS). Although it is compatible with BIOS, UEFI is expected to eventually replace it. The letter UEFI is most frequently used to pronounce the specifications. So let us check out the Advantages of UEFI to know more about UEFI.

What are the advantages of UEFI?

  1. Boot mode
  2. security
  3. Drives
  4. Graphical user interface(GUI)
  5. Supports multiple OSs
  6. Programming 
  7. Network support 
  8. Drivers

Let us have look at the advantages of UEFI and these are as follows

Boot mode

Microsoft Windows users have the option of running 32-bit or 64-bit UEFI, but experts advise that to prevent communication problems during runtime, the OS bit mode and the firmware bit mode should be the same.


For Windows 8 or later versions of windows, secure boot is a UEFI protocol. To ensure the integrity of devices and systems, the secure boot makes system firmware the foundation of trust. The goal is to prevent hackers from installing rootkits during the switch from boot to the operating system. The secure boot also makes it possible for an authorized user to remotely configure networks and troubleshoot problems, whereas a BIOS administrator is required to be present in order to do these things.


According to the UEFI forum, UEFI supports boot drives with a capacity of 2.2 TB and higher, Including drives with 1 9.4 zettabytes theoretical capacity. That is significantly more than the highest drive capacities at this time.

Graphical user interface(GUI)

Device drivers for motherboard hardware and connected peripheral devices can be added to the GUI more quickly and easily to UEFI.

Support for multiple OSs

Several operating systems can be installed in parallel. In contrast to BIOS, which only permits one boot loader. UEFI enables users to install windows OS loader alongside loaders for Linux distributions like Debian-based ubuntu. A certain function can be used even before the operating system starts. the user can choose which parts of the operating system should load.


Unlike BIOS, which is frequently combined with assembler and written in C, UEFI firmware is written primarily in C, allowing users to add or remove functions with less programming than BIOS.

Network support 

The UEFI can go online and like this, for example, be updated to a newer version.


In contrast to BIOS drive support, which is stored in read-only memory and requires tuning for compatibility when drives are changed or added. UEFI supports discrete drivers.
