I am trying to install Mountain Lion 10.8.2

[EDIT]: I am now getting the "still waiting for root device" error.I've tried using plenty of combinations of different boot flags. I am only able to use usb 3.0 because this laptop only has those kind of ports.if anyone has any suggestions that can help me out, please let me know

[OUTDATED] (I'VE GOTTEN PASSED THIS ERROR)
[My bios version is A13 and i have windows 8 installed. After i make a make a bootable usb drive (Sandisk cruzer 8gb) with the install file which is an iso file.
the problem i get is when I go into the bios setting and enable legacy rom loading and disable the UEFI boot and try to boot from the usb, i get a black screen saying this device is covered by a patent and then it lists my ethernet device (Realtek ...) and it seems like it is trying to boot from the network instead of the usb. I have also downloaded iATKOS L2 and tried the same thing, but i get the same problem. I managed to install the snow leopard on a virtual machine using virtual box, but i want the actual OS on my computer. Being able to install it on virtual box proves that theres nothing wrong with the install files. I have windows 8 loaded on a usb drive and it loads that one fine.
Does anyone have any sugguestions i can try?]

My Computer specs are:
Dell XPS 14 Ultrabook
Windows 8 Pro 64-bit Booting in UEFI
Linux CrunchBang booting from HDD
4GB Ram
Intel Core i5 3317U
Hitachi 500GB HDD
32GB SSD
Bios A13
Intel HD4000(no discrete graphics)
2 USB 3.0 (No 2.0)
No Disk Drive

External HDD: WD MyPassPort 500GB Already in GUID Partitioning scheme for mac.

also, can anyone give me advice on which guide i should follow for my specs?
My ultimate goal is to have mac OSX dual booting with Windows 8 Pro. I'm more of a windows person but i am a dj so i want to to have the stability that OSX provides while djing.
I already have windows 8 pro on a usb drive. It is a 100% legal copy that was given to me because i am a computer science student.

Thank you, any sugguestion and help is greatly appreciated.

Note: I do not have a disk drive because it is an ultrabook so some guides were not applicable to me. USB boots are my only option

Check the boot order in the bios.

Press F12 when you turn on the machine, and select the right device.

I can only link you the universal guide: http://www.insanelym...-for-beginners/

maybe a better question is...

How can i install mac without a disk drive?
i only have 2 usb 3.0 ports, no 2.0 ports
im able to get virtual box running a guest mac os x but im unable to install the guest additions that allow shared folders and it doesnt mount the usb for some reason so im unable to create the bootable usb through a mac os
I have tried trans mac but when i try booting off the usb, it gives me the same black screen with the same message.
when i made a bootable for windows 8(im planning on dual booting so this would help me fix the windows boot loader once the mac install messes it up), windows picked it up and ran the install immediately, but i didnt finish it since i dont have to right now.

can someone help me out?anyone?

Ok, just giving a quick update.
I installed the mac OS x bas system and a retail copy of ML 10.8.2 and followed one of the guides on here, but I got the Apple loaded screen with the small stop/prohibited logo. So i booted with -v and it I'm getting the "still waiting for root device" error.I have my SATA set to AHCI already. I don't know what to do.

Thank you

likely it needs sata device id injected in dsdt.

first identify what device id it is then we inject closest that apple uses with orange icon fix in dsdt editor.

im not sure how to do that.
do you mind helping me out?
a step by step would be nce, if you dont mind
also, this notebook only has usb 3 ports so that may be a problem. and the notebook is similar to a macbook air setup with the ivy i5 @1.7 GHz up to 2.6 with Turbo boost.both notebooks have no cd drives but most likely have the same chipset,i put that smbios.plist in my install usb

the sata is intel 282a
which i think is included so your issue is likely something else.

ive tried booting with combinations of different boot flags like
-v, -f, GraphicsEnabler=Yes/No, PciRoot=1, npci=0x3000, -x

still no luck

This is the guide i followed. maybe something from here is not suitable for my system?

[EDIT]: I retried the whole guide again and still no luck,
i then applied this patch, but the problem persists
