Do you have "secure boot" enabled? If so, disable it.

OK I solved this. My pc can't find USB when I start him. But when I restart the computer from win10 or from bios by alt + ctrl+delete and when the pc starts i plug in USB and then I rapidly press esc buton to get boot menu with USB OS and it works I'm so happy
