Hi, I copied the whole Windows 8.1 DVD into the hard and install.wim of Windows 7, then combined the install.wim of both Windows and made an ISO.
I started installation, after setup is starting screen it gave up an error about "invalid key".
Anyone know how to solve this? or any unattend.xml which can handle the Windows to skip the key and go forward.
Simply I want to made an single installer for Windows 8.1 and 7,
