    To do a total cleanup of my laptop and reinstall Win 7 32bit.

    It is a:

    Dell Precision Mobile WorkStation M6400.

    But a problem immediately with the error message:


    "A key driver needed for CD - DVD drive is missing"

    Then just my DVD / CD may malfunction (rails sometimes with CDs), I thought
    the fault lay there.

    Made a bootable usb, changed boot order via the F12 but may
    exactly the same error message still

    Googled around a bit and find many people who get the same error.
    But this will then stop when I do not really understand what the problem is.

    And have not found anyone who has a solution to the problem without more proposals for updating
    Driver / business software for DVD / CD player (updated)

    Others have suggested that you should disconnect the DVD / CD player entirely.
    Someone speaks about the jumper.

    Etc. ...

    Now I know soon not sure how I should do anymore.
    Is used to reformat / reinstall everything from 3.11 (a hundred years ago), Win 95, 98, ME, XP.
    However, not Vista.

    Much of the support is in English and here I get a little difficult with
    Judgement technical terms .. unfortunately.


    So the sum of my problem then is that I now sit with a bootable USB with Win 7 but will not be one meter ahead anyway.
    I also have windows disc but it does not work.

    What is known. malfunctioning unit should then be this, I think:
    HLDS HLDS GS20N 9.5mm Slot Load DVDRW SATA
    Firma Ware is uppdated.


    Thanks in advance.

    Hi A/,

    you say the firmware is updated but do you know which version? I found this one: Drivers and Downloads

    Failing that and apologies if this has also been mentioned, what about the SATA drivers? Some aren't contained within 7 and have to be installed via a USB drive or floppy.

    Harddrive is Seagate ST9320423ASG.
    But why should I update the hard drive if it is CD / DVD that I get the error on?
    Or is the sata drivers for my CD / DVD?
    Excuse my stupid questions: /
