System will not boot from CD-ROM
or DVD drive. The CD-ROM or DVD boot is
not enabled through the
Computer Setup utility. Run the Computer Setup utility and enable booting to
removable media and verify boot order settings.
Non-bootable CD in drive. Try a bootable CD in the drive.

detected or driver is not loaded. Drive is not connected properly
or not properly configured. 1. Reconnect power and data cables to the drive.

Cannot eject CD (tray-load unit). Disc not properly seated in the
drive. 1. Power off the workstation and insert a thin metal rod
into the emergency eject hole and push firmly.

CD-ROM, CD-RW, DVD-ROM, or
DVD-R/RW drive cannot read a
disc or takes too long to start. CD has been inserted upside
down. Reinsert the CD with the label facing up.
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.
