I want to share a folder between my host windows7 and guest Ubuntu but whenever I select add guest additions I get the following error:
Unable to mount the CD/DVD image C:\PROGRA~1\Oracle\VIRTUA~1\VBoxGuestAdditions.iso on the machine Ubuntu. Would you like to force mounting of this medium?
Could not unmount the currently mounted media/drive (VERR_PDM_MEDIA_LOCKED).
What should I do?
I got the following message on the terminal: ... Building the main guest additions module...done! Building the shared folder support module....fail!
Atleast tell me how I can enable copy and paste between the host and guest. I have changed the settings to bidirectional but still the copy/paste is not working
