Scenario is: You've decided to install Mac OS X on your PC and to move on from Windows forever. That being said, you made only HFS+ (Mac OS X Journaled (Extended)) partitions using Disk Utility and your partition table is GUID.
After some time, you realized that you'll need Windows, from some reason. But, problem is, you can't install Windows on pure GPT. Whatever you do, your windows installation is giving you an error that Windows can't be installed on GPT partition scheme.

Luckily, there is an easy way to make this possible. Thanks to Rod Smith, we have a command line utility called GPT fdisk:

GPT fdisk Tutorial
A gdisk Walkthrough

Enough talk, lets go to business.

In short, we'll need to make one hybrid mbr partition using gdisk.
First go and download disk for Mac OS X (available for linux and windows also):

Obtaining GPT fdisk

You'll need to partition some partition or to resize existing one with Disk Utility to FAT.

Then, fire up Terminal, and type

gdisk /dev/diskX

where X is number of your HDD.

In my case that's number 3. You can see, that it says

MBR : Protective

That means that you use pure GPT layout. Our goal is to transform it to hybrid in order to start windows installation. So let't do it.

Type p (to print the partition table)
Type r (for recovery & transformation menu)
Type h (for Hybrid transformation)

From there just follow the instructions.
In my case, partition number is also 3, so I type 3 for my partition to be added to the hybrid MBR.

I also choose to make that partition bootlable, so I type y on "Set the bootable flag".
Type p to print the partition table
Type o to print protective MBR data.

And finally type w to write table to disk and exit.

And that's it. To check you can type again gdisk command:

And as you can see, now it's

MBR: hybrid

Hopefully, now you will be able to run windows installation without any error.

If you create your USB stick with myHack, it has a MBR patch.

Think it's the graphicsmode, not the bluetooth. After loading the bluetooth the next step is getting into the graphicsmode.
Read this: http://www.osx86.net...512mb-help.html

[edit]
Just delete "NVDANV50Hal.kext" from USB /System/Library/Extensions
and boot with:
GraphicsEnabler=No -x -v

Did you make your install?
Booting with:
GraphicsEnabler=No -x -v
was only to install ML.

After install try the link in post #5

Thank you.

No problem.
I think you could run Lion or Mountain Lion easily on your hardware.

Back in a day, I tried all available versions of Windows, but I've always got that error that Windows can't be installed on GPT partition scheme. Only working fix for me was to transform to MBR of Hybrid MBR.

I was lucky...;)

I don't know if my way will work for everybody. Need more tester...

I found it accidentally when almost give up with warning/error from Windows installer. It said I can't install because the disk has MBR partition. In fact, I did format the whole disk as GPT with Disk Utility with only one partition (either NTFS or MSDOS-FAT). At that time I was thinking to reformat that partition using Windows installer, though reformatting there didn't let me proceed. Instead it worked with deleting the partition.

I repeated the steps when installing Windows 8 in my Z77 rig. Yes I know that Windows 8 can be installed on GPT disk. However maybe it was my bad habit formatting HDD with Disk Utility instead of Disk Management in Windows. So, I get the same error and deleting partition 2 (partition 1 is EFI) solved the problem.

I highly recommend not to use that tool. :D

Use this guide instead:

Finally I can install windows 7 on GPT partition.

But, I can't dual boot with Mac OS X.
Can boot only to Windows 7. So, run Mac OS, I use iboot.

Oh,....
I use the methode from tonymacx86 Blog: Dual Boot Windows 7 and OS X Snow Leopard Using Chameleon
but, in boot option I only can boot to mac OS X system. If I boot to windows 7 system, the result is " the boot selection failed ".
