While you are still reading this page, look up the key you would need to enter the BIOS/UEFI. This is essential as you need to change the boot order temporarily. This is likely either the Delete key or one of the F keys on top of the keyboard. Restart your computer, and repeatedly tap the key until you enter the BIOS/UEFI. You are going to want to look for the boot order. Once you find that section, you would want to make the thumb drive as the first boot option. This is important as you would need to boot from the thumb drive in order to see if this Linux version is right for you. Once you made your changes, Save and Exit. Your computer will restart and will boot into the thumb drive with the Linux OS?.
