LibreELEC on USB Stick

  • I have a Asus Chromebook with LibreELEC and I want to update to the newest version. It wont because it says not enough space. I know I have to reinstall off of a USB. I have made the file from here and loaded it on a 56G USB, my question is, can I set it up to boot off the USB all the time?

    Forgive me if this is a stupid question but I need help. :)

    Thanks
