I'm using these instructions to refresh Windows 8 (RTM) on my Samsung Series 7 tablet. When I got to the "Insert media" screen, I inserted a flashdrive containing only the files en_windows_8_x64_dvd_915440.iso
(the Windows 8 installer) and Key.txt
.
The first time I tried this, the tablet came back with the error message "The media inserted is not valid / Make sure to insert your Windows installation or recovery media."
Then I rebooted and tried again. Now I don't even get an error message--it's as if I didn't insert the flashdrive at all. The flashdrive is brand new and my PC recognizes it, so I doubt that's the issue.
Any idea how to fix this?
