I wanted to boot from the USB flash drive and proceed step by step as described in the document, but when I finally inserted the USB flash drive and booted, I could not identify the USB. Does the BootLoader not support boot from USB flash drive? But I see the manual can be started from the U disk, help to see where the problem, thank you
