If you boot Mac OS and have all HDDs show on the desktop, what is the Win10 icon name?
Try using this name as the default volume in Clover/boot if you want Win10 as the default OS to boot.
You will not have a timeout to automatic boot if the default volume listed does not match an existing volume name.
