Help Yosemite P9X79PRO i7 4820k GTX 970 keeps getting stuck

[Justtank]

Hi, I have tried lots of flags that i could find all over the internet. spent days but keep getting stuck with "AppleIntelE1000e(Info): AppleIntelE1000e:rx = 256, tx = 256"

Then proceeds to say "still waiting for root device"

tried npci=0x2000 / 3000 GraphicsEnabler=Yes / No , dart=0 , cpus=1, darkwake=0 but still stuck
Nv is disabled in bios and cant find whats up with the bugger. Worked a while ago before GTX 970 was supported but ran like a bag of s**t graphically, so 4 months later im having another crack at it

Screen shot in attachment.

Thanks for your help in advance.

Which USB port is using for bootable USB?? Avoid USB 3.0 ports and front panel ports.


What are the USB related options available on your BIOS and how they configured??
