I have run into an issue with the booting from usb stick as when I select it to boot from this I get the message "Reboot and select proper boot device".
I have one hard rive which is the one using windows 10 currently, I am trying to boot the ISO image file on my USB stick which contains Linux mint which I am trying to install.
The boot option 1 is clearly set to usb SanDisk. Also, if the usb stick is not in the computer when it restarts it just loads to my desktop.
