As for your question, you just press F2?F8?F9? and go into bios. Then choose usb boot and make it prioritized. I succeeded in doing this.
But, what i am more considering is that how could you install ubuntu on flex 5G, which must be powered by snapdragon8cx.
Teach me, PLEASE. I never succeed in installing whatever linux on a laptop powered by snapdragon8cx. The situation is that maybe some linux installer told me that installing is over ,successful. But they can never relly run successfully. For others, the installing is fail.
