How to Resolve Error 0x000000C4 Windows Server 2012 R2 on Oracle Virtual Box

When you try to install Windows Server 2012 R2 as a VM on an Oracle Virtual Box, you may run into this error message:

Your PC needs to restart.
Please hold down the power button.
Error Code: 0x000000C4
Parameters:
0x0000000000000091
0x000000000000000F
0xFFFFF801DB760A80
0x0000000000000000

Here’s a tip, that I found helpful to resolve the situation.

1. Launch Command Prompt and type in the following:

   "C:\Program Files\Oracle\VirtualBox\vboxmanage" list vms
   

   We executed this command to find out the name of our VM.

   

2. Then with the Command Prompt still opened, type in the following command to enable the CPU instruction CMPXCHG16B.

   "C:\Program Files\Oracle\VirtualBox\vboxmanage" setextradata "ITNOTA 2012 R2" VBoxInternal/CPUM/CPMXCHG16B 1
   

   

   Substitute the ITNOTA 2012 R2 with your VM name. You only need to enclose it with quotes if you have blank space in your VM’s name.

When you’re done, Restart the Virtual Machine again and you should see the Windows 2012 R2 installation screen this time.
