CD and DVD problems

If you can’t boot from a CD in the CD/DVD drive

•  Make sure the CD is bootable, such as the Recovery CD.
•  Restart the computer: click Start, Turn Off Computer, Restart.
•  If you want to boot from a CD whenever one is present, check the boot order in BIOS

Setup and change it.

1. Click Start, Turn Off Computer, Restart.

2. When you see the HP logo, press Esc to open the Boot menu. The default boot

order is (1) Hard Drive, (2) Floppy Drive, and (3) CD-ROM/DVD Drive.

3. Select the CD-ROM/DVD Drive as the boot device.

4. Exit the BIOS Setup utility.

• Test the CD/DVD drive with the e-Diagtools diagnostics—see “Testing Hardware

Operation” on page 111.

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, 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.
