How to install Windows 7 over existing Hackintosh build

I didn't intend to install Windows on my machine until the need to diagnose my Graphics Card arises. I was suspecting my Gigabyte GT640 card to be either having non updated bios or faulty after my Hackintosh build hung with the card but it worked breezing smooth after the card was replaced.

Furthermore, most of the diagnose, bios and what tools and utilities only available in Windows platform. Since I will need to test the graphics card in Windows, I will need to have Windows being installed on any of my machine of which I may slot in the graphics card.

Most of dual boot guide written on the net was made on freshly install Windows and Mac but not those completely install mac with all the apps inside.

I started with making space for the new Windows install on my GPT partition, resizing existing partition and created a new msdos partition and attempted to install Windows. It always says cannot install windows on GPT partition but I'm sure I've been reading about installing Windows on Mac so installing Windows on GPT shouldn't be a problem at all.

I was even cheated by a youtube video over the net which claimed windows 7 can be installed on GPT partition after performing 'clean' command in diskpart. Of course it can install but the partitioning had been converted to MBR. Luckily, I've been playing safe by making an image out of my Hackintosh install, of which later made me to write this article on how to install Windows on GPT partition over an existing Hackintosh build.

Thus why I decided to experiment till finally figured out how to do it, without jeopardizing your current install, or having to reinstall everything from scratch.

The only things you need:

  1. Mac OS X USB stick with Unibeast, Kakewalk or anything. I used Kakewalk for my build
  2. HFS+ formatted external hard disk

How to do it:

  1. Get into Mac installation boot - Creating a New Image over the partition of which Mac was installed not possible, that is why you would need to boot your PC using the Mac OS X USB stick and get into the installation boot option. Please also make sure your HFS+ formatted external hard disk is also plugged in to your UBS 3.0 port, so it's much faster, or else USB 2.0 if you don't have one.
  2. Backing up your Mac Build - Once you reached the install OS X page, open up Disk Utility. Click on your hard disk with Mac Install and click again on the partition of which you install your Mac OS X. Click new image and save it to your HFS+ formatted external hard disk as we're going to wipe your hard disk clean! Verify the size of the image and make sure if more or less like the size of the usage of the partition you install your Mac into
  3. Repartitioning - With disk utility, select what ever partitioning scheme you like but please make sure the first partition should be allocated to Windows with MSDOS format. You may allocate your mac install on any partition. I created 3 partitions of which the first one was for Windows, 2nd for Mac install and 3rd for data.
  4. Installing windows - Once the install windows page appeards, you will still encounter the unable to install Windows on GPT partition. You just need to click on advace, format the partition and that's it. Install Windows till complete.
  5. Restoring Mac - Boot using the Mac OS X USB stick and again using disk utility, restore the image from your external hard disk until complete.
  6. Restoring chameleon - Boot from USB stick and select your mac install. Once you're able to get into your Mac OS X install, re-install chameleon, and walla, your windows will automatically be listed in the boot option menu. You might wanna change the boot disk default in the chameleon plist file in folder Extra.

Then you're done! You may start dual booting your Hackintosh easily now!!
