Error code C4 when installing Windows Server 2012 on VirtualBox

Question

I am getting error code C4 when trying to install Windows Server 2012 on VirtualBox. I was able to install this a few weeks ago. However I had to install a fresh copy again. This time however I always get error C4 no matter what I try.

Settings I'm using:

• 1024 MB base memory
• 2 Processors
• 27Mb video memory
• I have checked to ensure Intel Virtualization Technology (vt-x) is enabled in my BIOS.
• Also I have SetExtraData as suggested in this post.

Any ideas as to what I am doing wrong?

Answer 1

fix C5 Error install Win2012 too (Disable Execute bit)

Answer 2

I had disabled "Execute Disabled Bit" in my BIOS in order to install Windows Server 2008 R2 on my VirtualBox.

Re-enabling it seems to have fixed the issue with Windows Server 2012.
