Error message question (P7, MacBook Air, Lion)

Sorry if this is a newbie question, but I am a newbie....
Running Parallels 7, Lion on MacBook Air.

Upon starting Parallels, an error window pops up as Windows 7 is starting. It says "Unable to connect CD/DVD 1".
I can then click on "OK" and everything runs as it should.
I assume it is because there is no CD/DVD drive, but I would love to know how to get rid of this message.

THANKS found in Knowledge Base....

 

Parallels menu -> Devices -> "CD / DVD 1" should be set to "disconnect". It's currently probably set to "Standard CD / DVD". As you don't have a DVD connected to your Air all the time, the poor VM is unable to find / connect that device.

Hope this helps!
