    -----------------
    Problem:
    My Windows 7 Professional "Explorer" tree (not Internet Explorer) no longer lists my CD/DVD ROM DRIVE under the Device Manager/Drives. It used to.

    I've checked the System Registry and it has lots of info about that ATAPI drive, but my system fails to find the "cdrom" driver (which is the one Windows 7 uses by default). It's not a 3rd-party driver.

    The tray on my CD/DVD drive opens and closes properly. Windows just won't recognize the drive, so I can't use it.

    I'm hoping someone can offer a 'manual' solution to get it working again. I do not want to spend a month to reinstall my OS and tons of hard-to-configure software. I've read countless other posts and solutions, both here and on MS's sites. The info on MS's sites is not even understandable. It's too vague and often doesn't even apply to my situation.

    Note: The error (7026) message is:
    "The following boot-start or system-start driver(s) failed to load:
    cdrom"

    Hello,
    First things first, if you access the BIOS, is the DVD / CD-ROM drive listed in the list of available boot devices? Since the tray can be operated, it means that the unit powers on, now we need to find out if the BIOS can detect it.


    Regards

    Thank you for replying.

    Now, I need to know what to do next since it is listed throughout the system registry, but is not showing up in the BIOS. From what I can tell, this is a software issue and not a hardware malfunction. I'm hoping I can have someone tell me if there's some option in Windows to place a check mark, or else some specific value to change in the system registry. What can I do next?

    Hi, well lets make sure it's not a filter problem ,go to start, search and type:- cmd right click on the returned cmd.exe and select "run as administrator' at the prompt copy paste:-

    reg query "HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}" > 0 & notepad 0 (press enter)

    Please post the notepad output here.

    I hope this helps. It's too bad I can't change the code 'box' dimensions to eliminate the scroll bar.
    Code:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
        Class    REG_SZ    CDROM
        ClassDesc    REG_SZ    @%SystemRoot%\System32\StorProp.dll,-17001
        (Default)    REG_SZ    DVD/CD-ROM drives
        IconPath    REG_MULTI_SZ    %SystemRoot%\System32\imageres.dll,-30
        Installer32    REG_SZ    storprop.dll,DvdClassInstaller
        EnumPropPages32    REG_SZ    storprop.dll,DvdPropPageProvider
        SilentInstall    REG_SZ    1
        NoInstallClass    REG_SZ    1
    
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}\0000
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}\0001
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}\Properties
    Thank you for replying. I had almost given up hoping that someone would reply. Please, let me know if there's anything else I can provide.

    Hi,well thats as it should be, without the bios detecting the drive you will never get it working since no drivers will be loaded at boot. Check the cable's and have the bios reset to defaults, or detect hardware to see if it's just a glitch, could be the unit is failing, they are cheap to replace.
