Here is how you fix. 1. click on the icon for vm hardware details 2. under CDROM click disconnect button (toggle to connect) 3. go back to vm and start That should fix your problem. Remember to connect when you need to mount a cd disk. Have fun. mpustel View Public Profile Find all posts by mpustel #3 2
