#3. Enable UEFI Mode

Now that you've successfully converted your MBR disk to the UEFI-friendly GPT partition style, the next pivotal step is to enable UEFI mode in your system. This step ensures your system fully capitalizes on the benefits of the modern UEFI environment.

Step 1. Power on or restart your computer.

Step 2.  Access the BIOS setup by pressing the designated key during the initial boot process (common keys include F2, F10, F12, or DEL).

Step 3.  Navigate to the "Boot" or "Boot Options" section within the BIOS menu using the arrow keys.

Step 4.  Select UEFI as the preferred boot mode.
