    I guy named pranjal_halo2freak from an another forum told my this-

    Hi reader Try out what i tell you

    There are a number of reasons why the operating system does not recognise
    your CD-DVD drive; it may, for instance, simply be a case that the
    connection to the CD/DVD drive has become loose. Alternatively, a driver
    problem may occur, or it may simply be a registry problem. Either way we
    try to address the problem here.

    The BIOS

    Without getting technical, the BIOS is a chip on your motherboard that,
    basically, starts the PC. It looks at what hardware and memory you have on
    your machine and checks that it can communicate with it prior to the
    Windows operating system kicking in. If the hardware is not being
    recognised then the BIOS is the first to complain.

    However, before we look at the BIOS it is worth checking to see that the
    cable connections to the CD/DVD drive are secure. This is simple enough to
    do, requiring you to simply open up your computer case and physically check
    that the ribbon cable is connected properly to the CD/DVD and the IDE
    controller on the motherboard. You also need to check that the power cable
    to the CD/DVD drive is also connected. If this is okay then is the CD/DVD
    recognised by the BIOS?

    To check this you can either watch the screen as you boot or enter the BIOS
    itself. Not all PCs display the boot options. This is because they have
    been disabled to make the boot process quicker. If your machine does show
    the boot options then you should see the machine first check the memory and
    then a list of devices should appear, something like this:

    Primary Master: WDC WD800BD 00CAA1

    Primary Slave: WDC WD800EB 00DJF0

    Secondary Master: NEC DVD RW ND 1300A

    Secondary Slave: None

    If the BIOS has recognised the CD/DVD then there should be an entry in the
    Secondary Master or Slave area. If it say's 'None' then the drive has not
    been recognised.

    With a None recognised drive you will need to consult your PC's user manual
    for details on accessing the BIOS (in most cases it is simply a matter of
    pressing the 'Del' key or some other key while the PC is booting. The BIOS
    menu should then appear. You should ensure that the configuration is set to
    'automatic' so that the BIOS automatically picks up the CD/DVD drive. Once
    again, in the BIOS menu, you should see the CD/DVD drive details displayed
    under the Secondary IDE Master or Slave sub menu.

    Driver Problems

    If the BIOS recognises the CD/DVD drive then the problem may be driver
    related. To check for this you need to take a look at the Device manager
    options in Control panel. You might also check the CD/DVD drive
    manufacturers' website to see if a later driver is available. If so
    download and install it.

    1/ Click Start

    2/ From the Start menu click Control panel

    3/ In the control panel window click the System icon

    4/ The system properties window will open

    5/ In the System properties window click the Hardware tab

    6/ On the Hardware tab click the Device Manager button

    7/ The Device manager window will now open

    8/ Look for your CD/DVD drive in the available list and click the + (plus)
    sign to expand the menu

    9/ Does the CD/DVD drive have a ? next to it? If it does then click on the
    Actions menu and, from the drop down list, select Uninstall. This will
    uninstall the CD/DVD drive.

    10/ After the driver has been uninstall, again click the Actions option and
    select the Scan for hardware changes option

    11/ Windows will now scan for any new hardware and should pick up your
    CD/DVD drive.

    12/ If that doesn't bring your CD/DVD back then you may need to edit the
    registry - see below

    Editing the Registry

    Before we go you should be aware that editing the registry can be
    dangerous, so before you begin make sure that you have a backup copy of
    your registry saved in a safe place (see Question 62 for more details). It
    is also wise to create a System restore point prior to changing registry
    entries.

    Now proceed as follows:

    1/ Click Start

    2/ from the Start menu click Run

    3/ In the Run dialogue box type: regedit

    4/ The registry editor will now open

    5/ navigate to the following key:
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11
    CE-BFC1-08002BE10318} and look for the Upper Filters value

    6/ Right click on the Upper Filter Value and, from the drop down menu click
    Delete

    7/ Next navigate to the following key:
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlclass{4D36E965-E325-11
    CE-BFC1-08002BE10318} and look for the Lower Filter value

    8/ Again Right Click on the Lower Filter Value and, from the drop down
    menu, click Delete

    9/ Finally exit the registry editor and reboot your machine

    10/ Hopefully, your CD/DVD drive should now be recognised
