There's nothing you can do in the registry. The CPU must support PAE, NX, and SSE2, if it doesn't, no Win8 for you.

Straight from Microsoft: If your PC doesn't support PAE, NX, and SSE2 you won’t be able to install Windows 8

Socket 478 P4s don't support NX. The oldest processors that will run Windows 8 are:

Most LGA775 P4s and Celeron Ds
Most Dothan-cored Pentium Ms

All Athlon 64s
All K8-based Semprons
All Turions

I believe the last version of Win8 that didn't require SSE2 and NX was the consumer preview.

I am aware that socket 478 CPUs do not support NX ,that is not the question, it is the registry I need to edit to remove this check at boot up.

"I am aware that socket 478 CPUs do not support NX"

And now you're aware (if you weren't already) that you MUST have a CPU that supports NX to run Windows 8. Since your S478 does NOT support NX, you can NOT install or run Win8, it's as simple as that. Editing the registry can only be done after Windows is installed, not before, & since Win8 will NOT install without NX being detected, you can NOT install Win8 on your S478 system. End of story.

I have already installed a 32bit version of W8 on a PC that was able to do so. It is obvious that this will not boot if this HDD is installed in the older platform. It is at this stage that the check is to be removed while still in the PC that created it. By opening regedit >HKEY_LOCAL_MACHINE >HARDWARE >SYSTEM >Current Control Settings > Control. This opens a list of items to modify, such as; NOEXECUTE=OPTIN These are the items that I need help with to skip the check at boot up.
