Cannot boot USB if microsd card present

[macjohnmcc]

I have a bootable USB that has Windows PE created using Windows 10 ADK. When I try to boot from it while I have a microSD card in the sd slot I get a boot error. Removing the sd card and rebooting works. Sadly I have put a backup of my computer on that microsd card and the bootable USB is my backup recovery media.

Any ideas to make this work or is it just not possible?
