Cannot boot back into Windows after successful Catalina install

After Success fully installing Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina 10.15.7 onto a SATA SSD. Windows 10 that is installed on an M.2 SSD is not an option in the OpenCore boot menu. If I change the boot order to have this drive boot first I get a screen that says "reboot and select proper boot device". After doing some research I suspect this is to do with OpenCore removing the efi partition on my windows drive but I am clueless as to what to do! Any help is really appreciated!
