URSim with Vurtualbox issue

I had the Sim working, but followed the procedure for creating a shared folder and it suddenly started asking for an ISO DVD on startup. I uninstalled, deleted config folder, reinstalled and tried again. Same window pops up saying no bootable media found and asks for DVD ISO location.

Any help on this would be great, thanks

Hi, from my experience, using FTP to transfer files between host and URSim is easier. software like FileZilla.
