Create A Universal Windows 7 DVD Which Contains All Windows 7 Versions From Windows 7 ISO

We all know Windows 7 has been released with variations in features as different versions like  Windows 7 Starter, Home Basic, Home Premium, Professional, Enterprise and Ultimate. It could be great if we can install all these versions of windows 7 from a Universal DVD but microsoft has reverted back to need to use a separate disk for each version, each DVD is a small 51 byte configuration file called ei.cfg which tells the installer what version disc it is.


The ei.cfg Removal Utility is a simple tool that will remove the ei.cfg from any Windows 7 ISO disc image, thereby converting the image into a "universal disc" that will prompt the user to select an windows 7 edition to install during setup.

What Does This Tool Do ?

This tool works by toggling the deletion bit in the UDF file table, eliminating the need for unpacking and rebuilding the ISO, which means that this is extremely fast (the process of patching the ISO to remove ei.cfg takes only a fraction of a second), and the process is easily reversible (running the utility on a disc image patched by this utility will restore the disc image to its original state).

    I tried this tool, but unsuccessful (at least for me).
    I think the best method is opening the ISO file using a tool like Magic ISO and deleting the mentioned file.
