Host: Win 7 x64 / i7-2600K / 16GB RAM / nVidia GeForce GTX 580 / Asrock Z68 Professional Gen3 Fatal1ty (Intel Virtualization Technology Enabled) / VirtualBox 4.3.18

Guests: Win 2012 R2 64bit ISO / Win 8.1 64bit ISO

Log files and PNG's attached for each instance below.

I have no problem running Win 7 64bit or pfSense or any other virtual box. All OS ISO's used were downloaded within the last 24 hours from Microsoft's website. The host machine is fully updated (Microsoft Updates / Software Updates / Drivers).

I even did the whole: Although I understand this was fixed in the most updated release, and is no longer necessary.

Any suggestions from the community would be most welcomed.

Enable PAE/NX under VM Settings, System, Processor and see what happens.

No change that I see.

Log attached for Win 2012 R2.

DEP!

Enabled it across all applications and this seemed to work.

Thank you for your time Socratis.
