Similarly, there was a .cfg file in the beta that could be changed which allowed
one to choose whether to install Home Premium, Professional or Ultimate.
7-Zip was able to extract the .iso into a folder where the file could be modified.
I had created a DVD from the original .iso and ImgBurn was able to extract the
boot image into an .ima file and save it. Presumably, you could just extract the
boot image from your installation disk. I then told ImgBurn to create a DVD from
the folder. The Advanced tab has the option to create a bootable disk and has a
place for specifying the .ima file. The Advanced tab is also where you can extract
the boot image and save it as an .ima. It was all trial and error, but it worked.
