Windows 10: This PC's processor doesn't support a critical feature (NX)."

Thanks guys, i noticed yontoo after posting and reading the speccy report, I've removed it. I had a look on the toshiba site, found drivers etc, but i couldn't find the bios update cereberus mentioned. I've uninstalled a few other old programes i noticed that i don't use anymore. I read further that with macrium reflect the version 5 doesn't uninstal properly, so i installed v6 overtop then uninstalled it. I am currently re trying w10 upgrade, i'll post the results when it's done.

 

See what you can find here - enter the model or serial number to get to the right support page.

FAQ: Where is my model and serial number on my Toshiba laptop

When I posted the BIOS 3.4 update - I didn't know your exact model (there are a few Toshiba Satelitte Pro P300 models), so I couldn't be sure it was for your machine

Once you know the sub-model, please put that in your specs - thanks

Windows 10 has finally finished installing, during my 6 attempts I believe the three key factors in overcoming my problems were

1 This PC's processor doesn't support a critical feature (NX)
Looking at the "Data Execution Prevention" tab under performance options stated that my laptop supports DEP,
so I ticked the "Turn on DEP for all programs" check box on and that solved that issue. which lead to:

2 page fault in non paged area pssnap.sys
I had Macrium reflect V5 installed, Macrium seems to install it's own version of pssnap.sys, which it fails to restore the original when you un-install the program.
The solution is to upgrade to version 6 and then un-install Macrium reflect. I checked the properties of both pssnap.sys files, identical size with totally different dates.
So the version 5 file is not compatible with Window 10.

3 UN-installing yontoo, may or may not have made a difference to the upgrade installation, but definitely not wanted on a P.C
I can mark this thread as solved. Hopefully someone else may find what finaly worked for me, may work for them.
Now I can put my 2nd hdd, wifi etc, back in.
Thanks again

 

Always like to see that Green Check mark and Solved on threads

Glad you got it sorted - Good work
