The Unified Extensible Firmware Interface (UEFI) is a newer standard that is replacing the traditional BIOS. UEFI was first released in 2005 and has been adopted by most major computer manufacturers.
The BIOS is a firmware that is responsible for the initial startup of a computer. It is responsible for loading the operating system and other essential drivers. The BIOS is stored on a small chip on the motherboard.
UEFI is a more advanced firmware than the BIOS. It offers a number of advantages, including:
- Faster boot times
- Support for larger hard drives
- Secure boot
- Graphical user interface

Is it possible to Convert BIOS to UEFI Without Data Loss?
Yes, it is possible to convert BIOS to UEFI without data loss. However, it is important to note that not all computers can be converted. If your computer is not compatible with UEFI, you will need to reinstall your operating system.
To convert BIOS to UEFI, you will need to update the firmware on your motherboard. This can be done by downloading the latest firmware from the motherboard manufacturer’s website and following the instructions.
Once the firmware has been updated, your computer will boot into UEFI mode. You can then configure UEFI to your liking.
