iMac 12,2 root patcher grayed out and install usb not showing up

My friend created a install usb for montrey so I can upgrade from high seirra the night I got usb it showed the montrey usb but it was late so I decided to do it in the morning now the usb doesn’t show up in the boot selector and the root patch button is greyed out
