We have Windows 8 Enterprise, using the ISO and license key from the MSFT Partner Network.
The ISO for Windows 8.1 Enterprise is already available. We downloaded it, and when try to use it the options are: "Keep personals files" and "Keep nothing".
No option to "keep apps and settings".
Any advise?
As @Ramhound mentioned, my issue was that the language of my Windows 8.1 Enterprise media didn't correspond to my installation.
Once I used the same language the option to "Keep Windows settings, personal files, and apps" showed up.
Side note: I do not know how MSFT is unable to include a simple warning message about this in the setup like "Hey... you are using a media with a language that doesn't match your current install".
