Instructions
1 Make sure you create a USB bootable drive with the installation files.
2 Create a Notepad text file and copy the following lines:
[EditionID]
Professional
[Channel]
Retail
[VL]
0
In this case because my installation is for Windows 8.1 Pro edition,
I’m specifying “Professional” in the EditionID, for the core edition use
the EdtionID Core.Professional
[Channel]
Retail
[VL]
0
3 Finally, save the text file as ei.cfg inside the SOURCES folder from the bootable drive you just created with the Windows 8.1 installation files.
Next you can continue to install Window 8 about same process as window 7.
