I've not really tried this myself yet, but a while ago I got this report from a madCodeHook user:

I had told him before that he needs to use InstallInjectionDriver and that he needs to enter his driver here:
HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal
HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network
Hope that helps?
