Booting from Windows 8 Release Preview DVD - error code 0x0000005D

The screen is black with the following text in white:
Your PC needs to restart.
Please hold down the power button.
Error Code:  0x0000005D
Parameters:
0x030F0209

Installing the consumer preview had no problems.

If I boot into Windows 8 (Consumer Preview) and run the Release Preview setup from the DVD manually, I get the "Your CPU is not compatible" error message.  My machine does meet the requirements as far as I know:  P4 2.6 GHz, 1.75 GB of RAM.


[Answer]
To install Windows 8 Release Preview on your PC, the processor (CPU) must support the following features:  Physical Address Extension (PAE), NX, and SSE2.  Most CPUs have support for these features, so if you receive this error, it is likely because the NX feature is not enabled on your system.

To resolve this error, follow manufacturer guidelines to enable NX (“No eXecute bit”), or the equivalent XD (“eXecute Disabled”) feature, within the BIOS security settings.

If the BIOS setting for the NX support option is not available on your system, you may need to contact the manufacturer for updating the BIOS.  Note that some older processors may not contain these features and will be incompatible with Windows 8 Release Preview.
