Configure BIOS

You’ll want to make sure you’ve configured your machine settings so that any USB sticks take precedence over the default Windows boot program.

• Shut down your PC.
• Start up your PC and press the hot key needed to enter BIOS mode (might be something like F10).
• Go to Boot > Boot mode and make sure your USB drive comes first in the list.
• Save changes and continue boot up
