Hallo @palatius, willkommen in der Community! Im Internet kursieren mehrere Threads über Upgrade-Probleme mit der E5700 auf Win 8/Win 10. Vieles spricht dafür, dass das sogenannte NX-Feature via BIOS für eine erfolgreiche Installation aktiviert sein muss: The problem you faced to install windows 10 was a new one for me too. Your CPU Pentium E5700 has NX feature (called XD) turned ON in BIOS. So, I thought the culprit may be windows 7 and it may not be enabling this feature for all processes. So I forced Windows to make NX (XD) feature be available to all processes. Then, Windows 10 setup was able to continue. This is exact order of commands I issued (though there may be other easy ways also). 1. Opened a command prompt with Administrative privileges 2. Typed "wmic OS Get DataExecutionPrevention_SupportPolicy" without quotes to see the current value for NX settings. It was 2 meaning NX (or XD) was enabled as OptIn (DEP is enabled for essentials Windows programs and services only and this is the default setting.) 3. Issued "bcdedit.exe /set {current} NX AlwaysOn" without quotes to force windows to edit boot options to make NX (or XD) available for all processes. 4. Rebooted the PC and run Step 2 to make sure the value returned is 1 (AlwaysOn) and it was the case. and the result is now you are on Windows 10 on the same PC 😉 (http://www.windows10forums.com/threads/windows-10-installation-failed-due-to-cpu-issue.1110/) Weitere Infos hinsichtlich der Voraussetzungen zum Upgrade mit vielen Tipps und Bildern gibt es bei ZD-Net: http://www.zdnet.com/article/windows-10-will-your-pc-run-it/ Grundsätzlich sollte für den E5700 also ein Upgrade möglich sein. Ich weiß allerdings nicht, was das BIOS so hergibt. Bei Medion sind die häufig etwas "kastriert" - leider . Gruß UFO
