Install fails my computer "doesn't support NX"

I have been trying to get a BIOS upgrade from ASUS, to eliminate this problem. Will have another go at it.

Windows 10 have the bad habit of ignoring any working driver and trying to replace it with generic Microsoft drivers from Windows Update. This explains your audio issue. The solution is to upgrade to Windows 10 and then replace the generic audio driver with the latest Windows 7 or 8 driver from manufacturer (OEM driver). If the OEM driver is older than the generic driver, Windows Update will replace it again at next update. To prevent it, you can use the show/hide tool to hide any driver updates. See tutorials.

PS: If you have an old Realtek AC'97 audio card (not newer HD models), the latest official Realtek drivers cause a BSOD. Search the forum for solutions. There is a solution for both 32-bit (install older Windows XP driver) and 64-bit (install older XP 64-bit driver).

Go to Asus support site, search for your device model (and revision if any) and it could have a new BIOS to download

this for all you guys who have a CPU supporting NX but the upgrade assistant says that you don't have NX. this solved my problem on an old Core 2 Quad.
Open CMD (Admin)
type in the following, after it's complete, restart, then try running the upgrade assistant. hopefully it should work!

bcdedit.exe /set {current} nx AlwaysOn

Yes I have seen this workaround, but this works IF and only if your CPU supports NX. If it doesn't it will not work! Believe me, I tried! The only way to install Windows 8 and 10 in an non-supported CPU is to hack the kernel and bypass the NX/PAE compliance check. In Windows 8 works until you run Windows Update and replaces the files. In Windows 10 works but you have to go at troubleshooting mode and select ignore driver signatures (test mode) in EVERY restart! No there is no way to make it permanent, I tried. Of course in Windows 10 an update can also replace the files and you have to hack again. Not really convenient...
