Reboot and select proper boot device or insert boot media in selected boot device and press a key Error

[rootww]

Hello. I am trying to install macOS on my desktop. I can't boot my usb sadly. I'm getting Reboot and select proper boot device or insert boot media in selected boot device and press a key error. How can I solve it.

My folders:
EFI/BOOT|OC
com.apple.recovery.boot/BaseSystem.chunklist and dmg.

What do you mean? I created a partition and I put EFI and com.apple.recovery.boot folders onto root folder of my USB.

Did you set the UEFI Boot in BIOS?
