If your Virtualbox or other virtualization software does not allow you to add 64-bit guest OSes, its probably because SMV is disabled.

1. go into your BIOS (Del / Entf key on startup)
2. go to OC (overclocking)
3. go into CPU Features
4. go to SVM Mode and set it to enabled and it then should allow Virtual Machines
