Boot From USB
- Turn on your computer and press Delete, F2, F10 or F11 (this varies by device) to enter the BIOS
- Use the cursor keys to find the ‘Boot’ menu or something similar
- Change the order so USB is at the top of the list as the number one boot priority
If none of those keys work to enter the BIOS, look out for a message on your monitor after pressing the computer’s power button. The message is usually at the bottom of the screen and says something like ‘Press F11 for boot options’
