Dell Optiplex 755 Kernel Panic

[iappleguy2]

Hello.
To start off, here are my specs:
Main System Type: Dell Optiplex 755
-Intel Core 2 Quad Q6600
-8gb RAM
-1TB WD Blue
-2TB WD Black (500gb parted for Mac)
-NVidia GeForce GTX 650
Notes:
-Hard drives are set to AHCI.
-VTx is disabled. Enabling it causes reboot loops.
-Everything else in the BIOS is set accordingly to other recommendations that I've seen on this site.
The issue:
It's a kernel panic. A few seconds after it finishes loading all the kexts and HFS stuff, I'm presented with this (ugly) screen. The USB was made with UniBeast using a App Store "purchased" copy of Yosemite. Post below if you have other questions. Any help is appreciated. I've attached a photo of the KP below.

These guys have been working on this model.......So have others in the forum with the different OS X's

A lot of info in their posts..........

The AHCI bios setting seems to cause kernel panics in Yosemite

"ACHI on the 755 panics the kernel and you have to use the LEGACY (ACHI) setting"

Good Luck

Ok. I set the drive mode to "Legacy" and Im able to boot into the OSX installer, but when going in to disk utility, none of my drives show up except my OSX USB drive. Here is how my drives are set up:
1tb - Windows 10 installed, nothing else.
2tb - Storage for files that cannot fit on 1tb, 500gb partitioned using a GParted LiveCD for OSX.

Did you ever figure it out? i have similar specs. Kernel panic on boot with ACHI in bios; no drive found in Legacy.
