Nitro AN515-58 Adding an external drive to boot

Rotem30046

I received a new nitro an515-58 model computer, without Windows, I inserted an external usb with an installation on it, but it did not boot, I entered the bot to change the order that the computer will read the usb first, but it does not appear at all in the lists, and no matter what I did, the computer did not recognize the the drive, and I couldn't find it in the bios or in the boot the things I already did: 1. I entered the usb bios on enabled. 2. In Boot Priority only 1 appears in the list and it is uefi_shell, and there is no way to change the order, because it is alone in the list. 3. I tried to change the port, to change the usb, I could not add the usb to my selections, I would love to know what to do. I note again that there is no operating system on this computer at all, I try to install and it does not read the external connections

maybe your usb is not properly configured to boot in uefi, use rufus

enable F12 boot menu

set a supervisor password in security tab

set boot mode to legacy and disable secure boot
