    You may be able to get a .iso from Dell here:

    Unfortunately it does not works.

    Did you check the .iso checksums to ensure you got a complete .iso download?

    Installing the tool doesn't require any info.

    No idea what you are saying.

    A screen capture would be helpful.

    I have an Optiplex 780 and when I use the official tool to get the windows 7 pro oa.iso (I had installed Linux on it and wanted to change it back to windows 7 pro) it says that an image exists but not for my machine what do I do?

    Borrow a Dell Windows 7 DVD.

    Or try to upgrade for free to Windows 10. I don't know if that is still possible.

    I checked Windows 10 when I got it and it said it was incompatible.

    Also, Where would I get a Windows 7 DVD?

    Edit: Can it be any Windows 7 DVD I know I have one somewhere
