I suspect it cannot find the ""device file"", because mount target directory is there. When downgrade to 5.1.14 it loads and runs with no problem. Host OS: Windows 10 Pro 64 bit[[BR]] Guest OS: Ubuntu 14.04 (scotchbox) 64 bit[[BR]] VirtualBox: 5.1.16 P.s. I can see some similar tickets created recently, but most of them are not with Windows host." defect closed guest additions VirtualBox 5.1.16 fixed mount, fails, shared Linux Windows
