2 windows boot manager in boot menu and the bootable usb not showing to run other os

Hi, recently i formated a notebook, but i want to instal deepin 15.3 on the hd and remove windows (this is easy i know how to do), but i have a problem... when i open boot menu, the boot menu shows 2 windows boot managers, and dont show the bootable usb, i tried with 3 usbs, i tried fat32, i tried disable the secure boot,i tried put a password to acess bios, i tried use the ufei but the linux deepin file dont show a efi file, ive tried burn the iso files with rufus, unetbootin and the booter usb of linux... the laptop is a switch 11, and i dont know how the bios work because its very simple bios, and i dont know when is the legacy mode. overall, i need help to run the bootable usb on that laptop because its impossible (for me i think) (when i open boot menu it shows 2 windows boot managers and dont show my usb ) ps: i have the boot order with the usb cdroom (the boot priority only shows usb hdd usb cd room windows boot manager and network boot piv4)
