Installing W10 I pass all requirements and get to the end of the installation process and get a notice that W10 cant be installed because my BIOS is missing NX. I had W10 installed previously no problem. The MOBO manufacturer is not willing to give support. (too old) I cannot find any setting in my BIOS to enable NX.

Thanks

Terry

Do you have the latest BIOS/UEFI?

Go into the BIOS and look for a security tab. You're looking for a No eXecute or eXecute Disable setting. If you have it toggle the option.

If you don't I believe you probably upgraded from Win7 to 8 to 10 before and you would probably have to go that route. NX/ND were introduced in Win 8

I never had W8. I dont have a security tab in the BIOS. I already upgraded to W10 before the cutoff last year and then reverted to W7 later on.

What I'm trying to say is Windows 7 didn't have that requirement and I believe the way you got around it before was because you upgraded (either to Win8, Win10, or Win 8 and then Win10).

I believe you're going to have to start with Windows 7 and upgrade to 10.

You can save yourself some trouble and check CPU-z to see if your processor supports NX.
http://www.cpuid.com/softwares/cpu-z.html

Look under Instructions for SSE2, EM64T (indicates PAE processor support), and either VT-d or VT-x (the NX part).

I have SSE2, EM64T and VT-x under Instructions
I currently have installed W7 Pro 32bit and 64bit on a different drive.

I love the below CAPTCHA !!! Where can I find it?

From the looks of your info this may not be a cpu or mobo issue. This is what my W7 CPUZ looks like.

Terry, the No Execute Bit option in BIOS won't necessarily appear under a Security tab, it could be under "Advanced", "Advanced Configuration" or similar. And it may have a slightly different name; e.g. Execute Disabled Memory Protection, EVP (Enhanced Virus Protection), No Execute Memory Protect, or EDB (Execute Disabled Bit).

Look under each section in BIOS for any of those names and enable the option if found.

If still no sign of NX in BIOS, you could try enabling it from within Windows:

Open an elevated command prompt (run as admin)
Type in or copy and paste the following command: bcdedit.exe /set {current} nx AlwaysOn
Then hit the Enter key
Restart the computer

That should run W10 without any problem. You said you upgraded to W10 and then reverted back to W7. Did you upgrade the 32bit or the 64bit? Since you have both 32bit and 64bit OS's connected then you may be running into a conflict between the two OS's.
I would change the boot order and make sure the 64bit drive is the one booting. I usually use Easy BCD but you can also try MSCONFIG. After getting the 64bit drive booting I would then unplug the 32bit drive and then run the W10 setup. I have a DVD that I boot W10 with and run setup from it, I just skip the product key entry, because MS should already have the activation, if the MOBO hasn't been changed.
All the things you see under CPUZ instructions are usually enabled with a 64bit OS but one will sometimes have to enable NX or No-eXecute. In other words this applies more to a 32bit OS.
Hope this helps and you get W10 installed. It is the future whether we like it or not.

It's part of the software. I could send you the php, but it would take manual intervention to make it happen on your end.

You might need to think about running Coreinfo from Sysinternals, it gives a lot more info about your processor.
To run Coreinfo I had to create a Desktop folder called Coreinfo and extract the Coreinfo files to it.
I then opened a elevated command prompt and typed in "C:\Users\Your User Name\Desktop\Coreinfo\Coreinfo.exe".
You can also open notepad and type this in and just copy and paste to the CMD prompt. You must have PAE/NX supported for W10 to install.
If you want to do this, then here is a link to Coreinfo.
https://technet.microsoft.com/en-us/sysinternals/cc835722.aspx

I ran this on another machine I have with a dual core Pentium processor and I had to do this
Extract Coreinfo files to "C:\"
Open elevated CMD and do a "cd C:\"
Type "Coreinfo.exe" at the command prompt
