Just to be clear on the flow when this occurs, you do the following on a VM 
that is shut down:

1. Select the VM in the VM grid.
2. Click edit and the edit VM dialog pops up.
3. In the General tab you scroll down a little until you see the instance 
Images widget that has the disk listed. You have 3 options:
  - Edit (edit disk)
  - + (add new row, that will give you the option to attach/create a disk)
  - - (remove disk)
You click - (remove disk)?
4. You get the exception?
