CPU Not Supported

Have Windows 7 sp1 and Windows 10 Build 10240 in dual boot.
On trying to upgrade windows 7, error message: Your CPU is not supported.
Have Intel Core2duo E7500 @ 2.93 ghz. Coreinfo utility says all NX, PAE & SSE2 are supported and enabled.
Window 10 preview has all along been running smoothly through various builds.
Please help

I have the same problem with CPU Core2Duo E8400

But when I do a clean install on another partition in same machine, it goes without hitch. Windows 10 gets installed and is ACTIVATED. But will it be a permanent activation or will expire after 15.10.2015.

I think you have a preview install on the other partition and this will expire.

Please follow this tutorial to provide the current operating environment of your machine.
Speccy - Publish Snapshot of your System Specs

Members can then look at the Speccy to see if anything stands out.

The first thing I suggest is to make it easy on the upgrade.

Get the machine to a simple base

• one drive, no external devices other than Monitor, Mouse and Keyboard.
• If you over clock, reset to the default clock.
• Establish a Clean Startup - basically disable all 3rd party items on the msconfig Services and Startup tabs
  Do NOT disable MS service - make sure the hide MS services checkbox is selected before you press the disable all button
  Troubleshoot Application Conflicts by Performing a Clean Startup - Windows 7 Help blog
• and Lastly, see if there is a BIOS update

I have no idea why these things would change the install flagging the CPU as unsupported, but they are basic trouble shooting.
Thanks

Am trying clean install too right now !!

I found a solution which has worked and upgraded from windows 7 sp1 to windows 10 today.

Instead of running regular setup,
Browse to Local Disk (C> $Windows.~WS > Sources > Windows > Sources
Double click the setupprep.exe file.


After running for some time advised to uninstall
1. Microsoft Virtual PC 2007
2. Daemon Pro Tools.


Meanwhile kept installer running


After hitting refresh button, the upgradation from Windows 7 SP1 to Windows 10 was flawless and smooth.
