If you start a guest operating system with the CD/DVD-ROM drive enabled you can connect/disconnect it and change media it accesses while running the guest OS.
Note: If the guest OS was started with the CD/DVD-ROM drive disabled, you should shut down guest OS first, then enable CD/DVD-ROM in the Configuration Editor (select the Enabled checkbox in the CD/DVD-ROM Options tab) and restart the guest OS.
All commands to control CD/DVD-ROM during guest OS execution can be found in the Parallels Workstation Devices menu.
To disable all CD/DVD-ROM operations while running guest OS click CD/DVD-ROM --> Disconnect in the Parallels Workstation Devices menu.
To reconnect CD/DVD-ROM again select CD/DVD-ROM --> Connect command in the Devices menu.
Data type accessed by the CD/DVD-ROM drive can be switched from a real CD/DVD-ROM to an image file and vice versa. Use CD/DVD-ROM --> Connect to and CD/DVD-ROM --> Connect image commands of the Parallels Workstation Devices menu.
Note: There is another way to perform all the actions described above. Right-click the CD/DVD-ROM icon
on the status bar to display CD/DVD-ROM context menu and select the required command.
