How to Change Your Computer’s Boot Order
The boot order is controlled in your computer’s BIOS (Basic input output system) or UEFI firmware, (Unified Extensible Firmware Interface) depending on how new your computer is.
To access the BIOS, you’ll need to restart your computer and press a specific key at the start of the boot process.
This key is generally displayed on-screen down during the boot process. For example, you may see a message that says “Press <F10”> to enter setup” or “Press F2 to access the BIOS.” Press the required key at the correct time and your computer’s BIOS will appear.
