Restart the computer
As it starts, press the BIOS/Setup key repeatedly (common keys: F2, F10, F12, Del, Esc)
If you see a logo screen, keep pressing the key until the BIOS/UEFI Setup screen appears
On some systems, use a Boot Menu key first (common: F12, Esc, F9) and select “BIOS Setup” or “UEFI Setup”
Wait for the BIOS/UEFI Setup screen to load
Use the keyboard to navigate (arrow keys, Enter, Esc, and the on-screen key guide)
Make changes only in the BIOS/UEFI settings you need
Save changes and exit (common option: “Save & Exit” or press the key shown for saving)
If prompted to confirm, choose “Yes” to save and reboot
If changes were not saved, repeat the process and use the save option again
