The error 0x0000005D occurs when you try to install Windows 8 on a new PC or when you use virtualization software such as Oracle VM Virtual Box or VMWare.

This error occurs because, unlike the Windows 7 operating system, Windows 8 is not fully compatible with all Pentium 4 processor models. To install Windows 8, your processor must support No Execute.

More specifically, for AMD processors, this function is called “No Execute (NX)” and for Intel processors “Execute Disable (XD)”.

Unlike Windows Vista and 7, Windows 8 (version 8400 or higher) is not compatible with all models of the Pentium 4 processor.

Indeed, Windows 8 requires a processor compatible with the following features: SSE2, PAE and NX bit. All Pentium 4 are compatible with SSE2 and EAP : the problem may come from the NX bit.

The shutdown error “0x0000005D” or “0x000000C4” also appears when starting a virtual machine from Windows Server 2012 ISO to install the system. The error occurs immediately after loading the installation files, before the actual installation begins.
