Windows 7: USB install flash drive and different versions

USB install flash drive and different versions

Here is my question: Will i be able to make a USB install flash drive with my Windows 7 professional DVD and use this flash drive to install all my family's Professional AND Home Premium versions and just use their keys to activate? That is the question. Thanks, it should be an easy one for someone.

The question is - does the Professional DVD contain the ei.cfg file? If so, remove it.

Extract all contents of the ISO to a folder on the deskop.

Browse into the folder where you extracted all the files to and open up the /sources/ folder and locate ei.cfg

The file can also be edited to a custom set of choices, but deleting it reveals all versions on the DVD.
