as Carlos said before, it probably will not boot. The guy in the video did not bring the proof, just saying you can try. For your reference: I tried it several times on some old boxes with his method and it failed ...
The requirement is checked at every boot by the kernel. If it is present but disabled Windows will try to force-enable it. If that doesn't work or there is no NX bit support in the CPU the OS will die with a 0x0000005D error.
exactly. Install worked so and so but after reboot, lights went down .. end of game ( at my end !!! )
