Eject an optical disc during startup

Hold down the mouse button while you hear the startup chime. Keep holding until the optical disc ejects from the drive.

NOTE: If your Apple device has an eject key, you can hold down this key before the startup chime until the disc is ejected.

TIP: Some optical drives have a manual eject hole. You will need a paper clip or an object with the same size as a paper clip. Insert the object into the eject hole; once it is pressed, the drive will manually release the disc.
