I attempted to make a clone of a bootable flash drive containing the Windows 10 operating system boot files via some bootable USB clone software. The clone seems to seems the same contents as the original, but the drive is not bootable. Am I missing something? Possibly bcdboot; See How to make cloned USB drive bootable? Is there a reliable bootable USB clone tool recommended? Thanks a lot.
