The issue is that the disk you created is not attached to VirtualBox as a removable USB drive, which is what Tails (or, more precisely, the live-boot tool that is used by Tails) is looking for. As far as I know, it's not supported by VirtualBox to add a disk as a removable USB drive.

This can be removed by unchecking the check-box.
While it looks useful, it is very frustrating so I advise people to open a web page with the help outpur ...

Host: Windows 10 1809 Pro 64 bit
Guest: Manjaro KDE 18.0.4 64 bit with 4.19.34-1-MANJARO kernel
