Did the update to 10.10.3, lost the ability to boot osx. Was the HD4000 issue, which I was not aware of, fixed without any research.
Fixed the boot issue, by reinstalling the full 10.10.3, managed to boot. Ran the HP installer for clover (latest one).
I do however, have no audio. I have done the boot with no cache, rebuild cache, reboot etc....
