    Your CPU is capable of NX it just maybe disabled.......though I am not sure why, just trying to think what else could be stopping it , is all.

    It will be in the CPU section, probably with SpeedStep and EIST settings , check your Manual as I don't know your MB, but it maybe called XD Bit too.

    Bit more info found online..........
    Some of the first 64-bit CPUs don’t have the required features to run 64-bit versions of Windows 10, even if they are 64-bit compatible. Specifically, Windows 10 requires PAE, SSE2, and NX. Microsoft has more information about this here. PCs will also need support for CMPXCHG16b, which some of the first consumer 64-bit processors didn’t include.
    The 64-bit version of Windows 10 will refuse to install if your CPU doesn’t support these things. If you’d like to check before you begin the install process, download and run CPU Z.
    “SSE2” will appear under Instructions if it’s supported. “EM64T” or “AMD64” should indicate that PAE is supported. “VT-x” or “VT-d” always indicates that NX is supported.

    On some older computers, you may have to enable NX (sometimes called XD) in the computer’s BIOS. If you receive an error about your CPU not being supported during the install process, visit your computer’s BIOS and look for an option titled something like “No eXecute bit (NX)”, “eXecute Disabled (XD)”, “No Execute Memory Protect”, “Execute Disabled Memory Protection”, “EDB (Execute Disabled Bit)”, “EVP (Enhanced Virus Protection)”, or something similar. Look under the “Security” or “Advanced” tabs somewhere in your BIOS for this setting.

    So i checked in BIOS to see if Intel VT-x was supported and it is. I then made sure that "Execute Disable Bit" was enabled. I changed some other things around that should be disabled like Fast boot. Does Secure boot need to be disabled as well?

    it can't hurt at this point AFAIK , just make sure UEFI and GPT are still used during the Install.

    You don't need VT-x unless you want to run Virtual Machines etc ? but I think they mention it cos it won't Enable, if NX / XD is OFF , so if you see VT-x in CPUz you know NX is ON , as CPUz does not show the NX bit set or not. That's my understanding , take it for what you paid for it

    Different SSDs and HDDs, different motherboards, different sata cables and different memory configurations. The only thing I can think of that's left is the CPU. Was the same CPU used on all the motherboards? I've never heard of a CPU causing this but there has to be a common denominator with all your setups that is causing this problem.

    Same cpu across the board. I've never had a bad cpu and this one registers in bios. I might be the issue but I highly doubt it.

    I sat on the phone with a really nice Newegg tech support rep Tommy. We will have another session tomorrow and I will post back here the results when we find a working configuration.

    I just RAM'd a CPU to Intel that would boot to the Bios but no further , so don't discount it 100 % , perhaps Newegg will send a new one ?

    I had an AMD K10 like that a good while back during a II x4 to II x6 upgrade had to exchange it and the replacement was fine
