Having a hell of a time getting Yosemite to work.
I successfully completed an upgrade install a few days back. I ran Multibeast and everything seemed fine - minus the sound.
I also updated the computer to the latest NVIDA graphics drivers.
I did a restart and since then, I haven't been able to boot and keep getting the "No Root Device" found.
In an earlier attempt to reinstall Yosemite (one of the few occasions I was able to get into the Yosemite install), only the USB drive showed up as the install location.
This was the first sign something was amiss.
At first the computer would load and eventually give me the "no smoking" sign after boot.
Now I can't even get that far and eventually the screen goes black.
Thinking it could be a multi part problem involving my video card (using a DVI connection) and something amiss with the boot sequence.
I've read through hundreds of posts and tried many variables -v -x -f but nothing will let me get into Yosemite.
Attached is a screenshot of the latest error.
I also tried removing my 560Ti Video card and booting using the motherboards video. If trying to do a hard drive boot I get the no smoking sign. When trying to boot into the USB Yosemite install i get in but the screen is totally garbled.
Using the "
GraphicsEnabler=Yes IPGEnabler=Yes" does not correct the issue
Using "
-v -x -f GraphicsEnabler=Yes PCIRootUID=1" i am able to get into the Yosemite install but the SSD Yosemite was earlier installed on is not listed as an install destination so I'm still at square one.
When doing "diskutil list" in Yosemite installer terminal the SSD drive (or my secondary Western Digital drive do not appear listed).
Any help is HUGELY appreciated!
