If this does not correct the problem, follow the action for “A CD or DVD does not work” on page 89.

A CD or DVD does not work

Symptom: A CD or DVD does not work.

Actions:

Verify that the disc is inserted correctly, with its label up.

Make sure that the disc you are using is clean. To remove dust or fingerprints, wipe the disc clean with a soft cloth from the center to the outside. Wiping a disc in a circular motion might cause loss of data.

Verify that the disc you are using is not scratched or damaged. Try inserting another disc that you know is good. If you cannot read from a known-good disc, you might have a problem with your CD or DVD drive or the cabling to your CD or DVD drive. Make sure that the power cable and signal cable are securely connected to the drive.

Symptom: Unable to use a startable (bootable) recovery medium, such as the Product Recovery CD, to start your computer.

Refer to your “Selecting or changing the startup device sequence” on page 70 for information on viewing and changing the startup sequence. Note that on some models the startup sequence is permanently set and cannot be changed.
