Error After Activating Virtualization on Bios

[brekler88]

Hello guys, im having a problem here.

Im trying to install CentOS7 on a virtual box. Im using Windows 7 x64 right now.

When i booted the VM and selected "install centos7" it only stays on a black screen, doing nothing after that, so i went on bios setup and activated the virtualization feature on CPU config.

Now when i boot the VM i get an error before it even boots.
Error relaunching VirtualBox VM process: 5
Images are attached.

Anyone have any idea why that ?
I suppose it needed to work with the virtualization feature, since its the only way to make a VM 64bits.
