How to solve 0x000000C4 error in Windows 8.1 installation in VirtualBox

If you want to try a Windows 8.1 system and do not want to install it directly on your computer, the virtual machine provides a good platform. Because of the daily work requirements, there are still a lot of virtual machines installed on the computer, and several virtual machines should be used together every day. There is not much more, so I tried to install Windows 8.1 In my familiar VirtualBox virtual machine.

The following error occurs during installation. The error code is 0x000000C4. It seems that this error also occurred when Windows 7 was first installed. At that time, it was because the Vbox version was low and there was no problem after the upgrade. After searching online, the solution was simple: you need to enable Vbox to support the CMPXCHG16B CPU command.

First, shut down the Vbox virtual machine, run the CMD command as an administrator on the host, open the command prompt, copy and paste the following command (including quotation marks) according to the installation directory of the Vbox on your computer) list all virtual machines installed on your computer:

"C: \ Program Files \ Oracle \ VirtualBox \ VBoxManage.exe" list vms

Remember the name of the virtual machine to install Windows 8.1. Louis is the last "Windows 8.1". copy and paste the following command (including quotation marks ):

"C: \ Program Files \ Oracle \ VirtualBox \ VBoxManage.exe" setextradata "Windows 8.1" VBoxInternal/CPUM/CMPXCHG16B 1

OK. Now, restart the Virtual Machine for installation. Is it okay? Although running Windows 8.1 on a virtual machine is not smooth, you can experience some improvements.
