The DVD-ROM drive takes longer to start because it has to
determine the type of media played, such as audio or video.
Wait at least 30 seconds to let the DVD-ROM drive determine
the type of media being played. If the disc still does not start,
read the other solutions listed for this topic.
CD or DVD disc is dirty. Clean CD or DVD with a CD cleaning kit, available from most

DVD driver.

3. Try a different brand of media. Quality varies widely
between manufacturers.
USDT computer boots too slow after removing a CD-ROM or DVD drive.
Cause Solution
