The BIOS recognizes the CD drive. But windows 7 does not recognize it. It is also not appearing in the Device manager. I also tried the registry keys but the lower filter and upper filter are not appearing.

Click on the start pearl, in the search box type: Disk man. select create and format hard disk partitions. Once the winodow opens you should see a list of drives connected to the Pc IE: C: system windows 7 OS . If you can see the dvd drive in the list, right click on it, click on: Change drive letter and paths, change the letter to one that is not used by another device or Hard disk drive.
Thank you. I dont see the dvd drive in the list of drives in the Disk Management as well
