Hi,
I have installed Ubuntu 18.04.2 within Virtualbox. Host system is Windows 10. All seem to work fine except that the Ubuntu image is stuck in size. I can drag the corner of the window to make it bigger but it just creates a border around the image which stays the same size. Same thing happens when I go full screen, same size image with a bigger border. I tried installing "Insert guest additional CD image" and thought I had but, it made no difference. I then tried installing it again and got the following error message:
Unable to insert the virtual optical disk C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso into the machine Testing.Could not mount the media/drive 'C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED).
I take it this means the the installation has failed so any advice would be appreciated.
