Restart Your Computer

Enter the BIOS/UEFI Settings

During startup, press a specific key to enter the BIOS/UEFI settings. Common keys include F2, F10, DEL, or ESC. The exact key depends on your motherboard manufacturer.

Look for a message on the screen during startup that indicates which key to press.
