OpenCore post-install issue with booting windows again

Hi, i managed to install Catalina on my PC (see specs below). I have one M2.sdd with windows and SSD for hackintosh. Now Im able to boot osx if USB is attached and i wanted to configure dual boot. I followed the steps in:

But i don't see the USB stick. If I also mount the SSD with Catalina, the mounted disk is empty... So how can i now configure the OpenCore and copy my config from the USB? The mouse and keyboard attached in USB work without any problem
