6578d1339062148t-vbox-ose-windows-xp-vista-7-8-64-bit-virtualboxAfter I completed the install of my Windows Server 2012 in Virtualbox, I started getting this weird error code: Error code: 0x000000C4. I started doing a bit of research, and found out the virtualbox contains a bug with this version of server 2012 64 bit. Here’s the exact error when booting the OS.

Your PC needs to restart.
Please hold down the power button.
Error code: 0x000000C4

After doing a bit of research I came upon this solution. Notice that if you have spaces either in the VirtualBox machine name or the path, you must surround it by quotation marks “”.

VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1

and if your running windows

"c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1

and here’s the link to the site.
