CD and DVD problems
If you can’t boot from a CD in the CD-ROM drive
• Make sure the CD is bootable, such as the Recovery CD.
• Restart the computer: click Start, Shut Down (or Turn Off Computer), Restart.
• Make sure the CD-ROM drive is selected as the boot device—see “To change the
boot device“ on page 38.
• Test the CD-ROM drive with e-Diagtools—see “Testing Hardware Operation“ on
page 157.
If the computer cannot read a CD or DVD
• For a single-sided CD or DVD, make sure the disc is placed in the drive with the label
facing up.
• Wait 5 to 10 seconds after closing the tray to give the computer time to recognize the
disc.
• Clean the disc.
• Restart the system: remove the disc from the drive, then click Start, Shut Down (or
Turn Off Computer), Restart.
• If you created the CD on a CD-RW drive module, try using HP certified media. Read
and write quality may vary for other media.
If a CD or DVD plays erratically
• Dirt or smudges can cause a disc to skip. Clean the disc with a soft cloth. If the disc is
badly scratched, it will have to be replaced.
• Some DVDs include software called “PC Friendly”. You do not need to install this
software, as it can make the player unstable, and cause errors or erratic play. If
needed, uninstall the PC Friendly software and restart your computer.
If a DVD movie stops playing in the middle
• The DVD may be double-sided. Open the DVD tray and read the text near the center
hole of the disc. If it says Side A, flip the disc over, close the tray, and then press the
Play button to continue playing the movie.
• You may have accidentally paused the DVD movie. Press the Play button to resume
playing the movie.
