CD or DVD drive not found in Windows 7

If your CD\DVD drive is identifed by your BIOS but not by Windows 7 then try the following:

  • Run regedit.exe
  • Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ControlClass
  • Delete both UpperFilters and LowerFilters in the right-hand pane
  • NB: Leave both the UpperFilters.bak and LowerFilters.bak entries

If this doesn’t work then try resetting the drive letter using the following:

  • Run the Disk Management tool
  • Choose ‘Create and format hard disk partitions’
  • If the DVD drive is present then right click it and select ‘Change Drive Letter and Paths’
  • Click ‘Change’ and select a new letter
  • If the CDDVD drive is now visible in Explorer you can change the letter back
  • If it is still not visible then reboot and it should appear
