HELP! Installed but can't boot into Yosemite from the USB

[JPluth]

I could boot into the installer with no boot flags, (I used the upgrade guide) I installed but can't get into the operating system.

I have tried -x-f-v, graphicsenabler=yes and npci=2x2000

Boot with -v (verbose) and post a pic of the screen where it hangs. Did you install over an existing Mavericks?

 

[JPluth]

Yes over a mavericks install, here it is with

-x-f-v npci=0x2000

 

[JPluth]

Here is the screen shot

 

[clipper99]

make sure you have a space between those boot flags right? (I think)

-x-f-v

should be

-x -f -v npci=0x2000

EDIT:

graphicsenabler=yes is also case sensitive, should be

GraphicsEnabler=Yes

 

[JPluth]

Yea, I know all of that, I was just lazy typing it here

 

[clipper99]

Ah ok!

From the the looks of that screenshot I'd say you need to install the ACPI rollback for the 5-series motherboards. But of course that means you'll need to get to the desktop to actually install it from Multibeast 7. D'oh!

Anyone?

I went ahead and did a fresh install, I could boot but again after multicast had the same issue
