I've spent months reading the forums and downloading etc. and I've finally got round to trying to boot with a Yosmite build stick and so far it reboots. Will be reading more again tomorrow now I know what is happening.

 

This screenshot of yours makes me think this is a BIOS issue but hard to know without more info. I'd suggest read the guid and make sure all BIOS options are set correctly then try again.

I have used this flag to fix this issue

 

/amd npci=0x2000 -v 

 

note sure if your using AMD cpu please make sure you are using the correct flag for it 

 

 

good luck
