Okay, let's do the Setup 1.x first... I did everything that you said, but in the V: I don't have the file \config\pci.bat

But when i start windows i have the option of windows 7 or DIY

In DIY it says this:

(DRV=C, RAMD=R>RDISK_10-MB. Copy c:\config->R:\config (clobbered USB ctrl p.)

DETECTED dGPU=10de : 0fd5 (NVidia)

CUTEMOUSE v2.1 beta4 [FreeDos]. Error: device not found.

I'm already seeing that windows 8 will be easier to make no?

And how you installed windows 8? there's only upgradable versions

I set up an XP VM, ran the upgrade program on it, waited for it to download the 3 odd GB installer, and copied it to a USB stick. Then booted off that and used the license provided by the installer.

Why did you need xp vm?? and I can only install it with professional or better version no? I only have home premium

Ok, I download the upgrade and put it in a usb.

But can I get the upgrade using my win 7 home premium?

I'm understanding this:

Download the upgrade, put it on a usb stick and then boot off from it in the efi, right?

But here' the thing, the upgrade only works to upgrade, how I'll install it on nothing? unless the version you download is the FULL, but it needs to confirm first you have the previous windows

Here is another type of question: Using this method you were able to use the screen of the laptop? For that you wouldn't need some kind of Virtu MVP?

Need a winxp (any - home, pro, doesnt matter) vm for the mictosoft upgrade app to charge you 39$, give you a key and download the installer (except you don't let the installer reboot And run you pinch it's files instead).

I've found a good tutorial, is this what I gotta do? http://paullabs.wordpress.com/2012/02/29/windows-8-on-mac/

But instead of step 4 I use your steps of creating an EFI?

I think I understand something now, I need to update my current win 7 to win 8 before the refit right? So these 2 processes are completely separate?

Independently of where or how I have my win 8 on my pc, the code you created "startup.nsh" will work? that's it?

I'm sry for all the questions, but I really want this to work and I've been trying for almost half a year. And I really need all the aswers for all this questions so that I can understand.

I used these instruction but had less trouble so I could skip some steps.

No Bootcamp and "# diskutil resizevolume /dev/disk0s2 250G" beeing the most important part.

If you cann't make it work I'll describe my steps.

Your tutorial explains how to create a BootCamp installation.

Ok, I'm gonna put here those instructions with my questions in red right next to it.

But before that there's another step that I need help.

In my mac I have 2 partitions: 1. Macintosh HD and 2. BOOTCAMP

I need to know if this is what I need to do:

1. Log in windows 7 on bootcamp

2. Wipe my usb drive using this code:

run command prompt as administrator

> diskpart

> list disk

(check which disk number your USB disk appears as, use it in the next commands)

> select your-usb-disk-number-from-previous-step

> clean

> convert gpt

> create partition primary

> select partition 1

> format quick fs=fat32

> assign

> exit

3. Buy and download Windows 8

4. Put ISO of windows 8 inside that usb drive

5. Go back to Mackintosh HD

6. Delete BOOTCAMP partition along with it's windows 7

Well you just need a Windows 8 DVD or USB stick so you can install it.

eg. I downloaded and created a DVD from within Mac OS X.

You could go to a store and grab a copy too.

I'm wondering ... how well works your internal graphic card in EFI mode without your eGPU ?

I'm monitoring this thread (Win7 x64 booting natively via EFI (no bios emulation) - Page 34 - MacRumors Forums) in order to install Windows 8 in EFI mode. For me everything works well except the fact that my Radeon 4850 in my iMac have no ressources. In Bios mode everything fine except I prefer windows access my computer in "raw mode", not filtered.

I found that the use of the command mm 0003003E 8 -pci give me the possibility to have my Radeon to works with the Generic Graphic Card driver but if I use the real driver (from Windows Update), Windows said the device has a problem and didn't start (MacRumors Forums - View Single Post - Win7 x64 booting natively via EFI (no bios emulation)).

Thanks for your support.

How did you downloaded from within osx? you don't need to run that program they tell you to download?

And matters the type of windows you get?

And I need an answer about the deleting bootcamp

I've downloaded win 8 and put it on a dvd

Now I delete the bootcamp (win7) partition from within osx?

Yes. Remove it using DiskUtility but don't create a new Partition yet.

Open Terminal and enter "sudo diskutil resizevolume /dev/disk0s2 250G" (replace 250G to and size you like) to resize your Mac OS X Partition.

Next restart with your Window 8 while pressing the Alt/Option Key and select EFI Boot.

Your Windows installation should run in fullscreen resolution (2880x1800). If its lowres something went wrong.

That is to size my macintosh hd I already have?

Wouldn't it be easier to size my macintosh hd via diskutility without creating a new partition? Like this:


something happened when i deleted my bootcamp via Disk Utility, it showed a disk0s4 in it's place, what I do about this?


And for last, when I need to do the process you mentioned before:

1. Install rEFIt

2. In Mac OS mount the EFI partition using terminal:

3. Create a textfile called "startup.nsh" in it's root:

4. Reboot while eGPU is connected (SW1=1) and select "start EFI-Shell" in rEFIt.

"startup.nsh" launches and Windows 8 starts up with eGPU enabled.

No. Merge all Partitions in DiskUtility and resize it using the terminal command. you'll receive problems otherwise. just do whats written.

The rEFIt parts should be done after installing windows. It doesn't really matter anyways.

Okay, install windows in which place?

I have 4:

partition 1: EFI (probably because of previous try i've done)

partition 2: 558.8 gb (I believe its osx here, i've put it to 600G

partition 3: 619 mb (don't know what this is)

Unnallocated space on unit 0: 140.1 gb (that's the rest of my ssd)

After installing I go to apple and download the bootcamp drivers?

This should be your Mac OS Recovery disk

Unnallocated space on unit 0: 140.1 gb (that's the rest of my ssd)

This. Windows will create all needed Partitions

It shouldn't help to have all the drivers ready? sound and etc?

installation is done

when i reboot and press alt it shows macintosh / recovery / EFI Boot (this means it's all set?)

what the next step?

When I try to get in the win8 it freezes on a black screen and then says it got error and a sad face.

Then It restarts and starts win8

Yeah sure you want to install your drivers at some point. Especially the Apple ones ... internal sound wont work though due to those bugged Intel Chipset Drivers. Only HDMI and USB audio works.

EFI Boot is your windows partition so everythings fine. You can try to boot with your eGPU connected and powered on. Some GPU don't need the EFI-Shell fix.

If it doesn't work create a startup.nsh as described in the OP.

Regarding your blackscreen: It's probalbly because of intel drivers. Boot windows into DOS Prompt or get a demo of Paragon NTFS so you can remove the following intel driver -> "c:\windows\system32\drivers\igkmd64.sys"

Your LAN and WLAN should work plug and play. Didn't had and haven't heard of any problems. Even without BootCamp drivers.

Maybe you could try to connect your MacBook by LAN and update the broadcom drivers via Device Manager or download the current version on their website.

      Hi everyone. New to Tech Inferno. You can call me Stu. Nando asked me to post my setup and results which I'm happy to do.
      I'm going to keep this as simple as possible since this eGPU project has been just that, simple and awesome. In my eyes, this is where the eGPU game ends. Thunderbolt 2 (and TB3 coming soon), full-size chassis, fastest single GPU on the market, running at desktop speeds. I suppose the only caveat is cost but considering I only need to upgrade my GPU from this point on, it’s worth it. I live an hour away from Sonnet's headquarters in California and decided I had waited long enough to complete my eGPU experiment. The results surpassed expectations.
      Feel free to scroll down for specific benchmark and game results.
      Key Points
      Completely plug and play. Standard Bootcamp 5.1 install (*see below), connect everything up, boot Windows, install drivers, you’re done.
      eGPU vs Desktop performance: 85-90%
      Gaming: Max out virtually any game. 60FPS+ (with a few exceptions. e.g. Black Flag has weird PhysX that kills performance so I turn it off)
      Discrete 750M graphics = No Optimus/Internal display support. MBP w/Iris only = Optimus support but not fully plug and play (**see below)
      Simulated Optimus FPS loss: 5-20% (window drag method)
      eGPU Setup Cost (Not including MacBook): $1500 to $2000 depending on GPU purchase
      *It appears only 2013 MBPs w/newer PCIe flash storage defaults to UEFI/GPT-based windows installation with Bootcamp 5.1 .. 2012 rMBP (and possibly other macs/notebooks) will not format to GPT and therefore no plug and play
      **Conclusive Results for 2013 13" MacBook Pro - Optimus - Thunderbolt 2 - Plug and Play
      2013 Macbook Pro 15” w/GT 750M [email protected] 16GB-DDR3L 512GB SSD US$2599
      Sonnet Thunderbolt 2 III-D Chassis (US$979)
      EVGA Nvidia Geforce GTX 780 Ti Superclocked 3GB (US$720)
      Corsair RM450 (Silent) Power Supply (US$100) for 8-pin cable only (Jumped the 12V rail with small piece of metal. Google it)
      Standard Bootcamp 5.1 (UEFI) Installation
      Windows 8.1 w/latest Nvidia drivers
      MSI Afterburner with custom fan curve, gpu temp/fan speed match (e.g. 68 degrees/68% fan speed)

      Hello guys, I have iMac 12,2 with TB1 and i want to upgrade it with eGPU. I decided to buy TH05 or TH04 (it doesn't metter). But I read that it's a problem to buy it now. Are there still any offers of TH05/TH04 or I need to buy somthing like: Echo express boxes(Sonnet - Thunderbolt Storage, Adapters & Expansion Boxes) or AKiTiO Thunder2 box and etc. ?
      Thanks in advance.
