First, turn on the computer, enter the system, turn on "My Computer" and see the drive letter of the CD-ROM drive.
Right-click the drive letter of the optical drive, and then click Eject in the drop-down menu that appears. Or directly press the open button of the computer CD-ROM drive, and the CD-ROM drive will automatically pop up.
Put your math CD on the tray of the CD-ROM drive. Align the center of the optical disc with the center of the optical disc drive bracket. Press the position where the central disc matches the optical drive bracket gently and forcefully to fix the optical drive on the optical drive bracket.
Right-click the drive letter of My Computer, and then click Close. If your computer doesn't support right-clicking to turn off the CD-ROM drive, press the CD-ROM drive switch to turn off the CD-ROM drive directly. It is not recommended to push the optical drive bracket directly into the optical drive, which may cause the bracket to tilt for a long time.
Wait a minute, wait for the CD drive to read the CD. At this time, the CD-ROM drive symbol will generally be displayed on the drive letter of the CD-ROM drive, which proves that the reading is successful. We can open the CD and see its contents.
