This document applies to HP computers with Windows 7.
When you try to burn or read a disc, nothing happens or an error stating that the drive cannot be found appears in the CD/DVD burning software.
Use one of the following sections that best describes your situation:
If a window does not open when discs are inserted into the drive and the drive does not appear in Windows Explorer, then the drive is not being recognized by Windows 7. Use these steps to troubleshoot this condition.

NOTE:If you have a new notebook computer, make sure the computer actually has a CD/DVD drive. Several models of notebook computer do not come with CD/DVD drives and must use an external USB drive.

NOTE:If you have upgraded your computer to Windows 7 and the drive was working before but is no longer working correctly in Windows 7, you can save time by starting at Step 6
to remove the upper and lower control filters from the registry.
Step 1: See if the drive appears in BIOS
The BIOS in your computer manages all communication between the hardware components and the operating system. If the operating system does not recognize the CD/DVD drive, check the BIOS and see if it is recognized there. To check the BIOS, use one of the following sets of steps, depending on the type of computer and the version of BIOS you are using:
- Turn off the computer and wait five seconds.
- Turn on the computer and immediately press the F10 key repeatedly until the BIOS Setup Utility screen appears.If BIOS does not open using F10 , repeat the process using the F1 key instead.
- Use the arrow keys to navigate to the System Configuration screen.
- Select Boot Options and then press Enter .
- On the Boot Options sub-screen, select Boot Order and then press Enter .
- In the Boot Order list, look for a CD/DVD drive entry. Depending on your notebook model and specific CD/DVD drive, the entry name indicates the exact type of disc drive you have (for example, it may read Internal CD/DVD-ROM Drive ).
- Press Esc and then press Enter to Exit BIOS.
- Turn off the computer and wait five seconds.
- Turn on the computer and immediately press the F10 key repeatedly until the BIOS Setup Utility screen appears.If BIOS does not open using F10 , repeat the process using the F1 key instead.
- Use the arrow keys to navigate to the Main tab.
- Look for a CD/DVD drive name next to one of the Channel Device listings.
- Press Esc and then press Enter to Exit BIOS.
- Turn off the computer and wait five seconds.
- Turn on the computer and immediately press the F10 key repeatedly until the BIOS Setup Utility screen appears.If BIOS does not open using F10 , repeat the process using the F1 key instead.
