Partition Table Error

[BabaYagaJW]

During the installation process, I suddenly get a Partition Table Error. Here is a quick summary of what I did, incase I did something wrong. (Very likely)

I purchased Mountain Lion from the App Store using my iTunes Account. I tried to find a newer copy, but Mountain Lion was the newest I could find to buy, so I used that one. I was able to use Unibeast to create the boot USB. This went well, no errors.

I set the bios to LOAD Defaults and Boot using AHCI Mode. The installer would NOT pop up, so I had to boot using the "-x" command.

I can begin the install process, but then after about 1/2 through, it says:

I'm currently getting an INVALID Partition Table

My Current System:

Dell 6430u
CPU: Intel i7 3687
BIOS Revision: A14
Motherboard Manufacturer: Dell Inc. | Model: 0JPWJ2 | Chipset: Intel Ivy Bridge Rev. 09
Southbridge: Intel QM77 Rev 04 | LPCIO SMSC
Graphics: Intel HD Graphics 4000 Rev9

This so far has been a "pet project", but i'm pretty stuck. I have used the following guides:

https://www.tonymacx86.com/threads/dell-latitude-6430u.104618/
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/

Those have given me a few tips on what to do ONCE it works, such as run multibeast, then find the rest of my KTEXT, however, I'm pretty stuck on this one.

Don't hesitate if I need to post more, just let me know. I appreciate it.

Update: Motherboard Information (See Above). I pulled that information from CPU-Z. Syteminfo just said it was a Dell Brand.

Follow the Clover guide linked from the FAQ.
http://www.tonymacx86.com/el-capita...faq-read-first-laptop-frequent-questions.html

Although you should read the FAQ for an overview of issues, the Clover guide is linked from the first question: "Q. Where do I start?", just after the bold face "Clover Guide".
Here is a direct link, just to be clear:
https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

Also, your profile must be filled out with complete details as requested in the FAQ, again under "Q. Where do I start?". All seven details requested are equally important.

And if you have an issue (after following the guide), or on any other problem, you must provide a detailed description of the problem including information that helps us understand what you're doing. Always attach "Problem Reporting" files as per FAQ.

The required files and data are fully detailed in the last question in the FAQ:
"Q. What are typical "Problem Reporting" files?"
