How to get Windows 7 set up on your Apple computer

Installing Boot Camp 4.0 on Windows 8
The latest Boot Camp drivers won't work properly with the Windows Developer Preview, since the built-in OS check detects that you're running Windows 8 (NT 6.2) instead of Windows 7 (NT 6.1), and the compatibility assistant is no solution. You are stuck with "Boot Camp requires that your computer is running Windows 7".
Here's the solution: First, download and install Microsoft's ORCA MSI editor. Fire up Orca and use it to pen the "BootCamp.msi" (32-Bit) or the "BootCamp64.msi" (64-Bit) installer files, which are located under the "\Drivers\Apple" folder in your Boot Camp directory (make sure to create a backup of the original file, just in case).
Under the "Tables" section, you'll find a category called "LaunchCondition."
Right-click on this entry and select "Drop Table". Save the MSI file and try to launch either the BootCamp.msi/Bootcamp64.msi or if that doesn't work the setup.exe found in the root folder. This should get all your Boot Camp drivers installed.
Step 6: Update your drivers!
Since Apple uses standard hardware components (mostly), you won't have a tough time finding suitable drivers, though some of them require a bit of searching and tinkering.
This is why I only recommend hunting down and downloading (and in some cases even modifying) drivers if you've got problems with games running unusually slow on your graphics card or when the Wi-Fi connection starts acting up.
The list of potential drivers for all the variety of Macs (Mac Pro, MacBook Pro, MacBook Air, Mac Mini, iMac) goes on and on, so I'll just compile the most popular here:
Intel chipset drivers: Basic chipset drivers which include the latest IDE/SATA/AHCI drivers, sound drivers and other enhancements.
Intel HD Graphics (onboard GPU) Drivers: These drivers are updated every couple of weeks, which quickly made the Boot Camp 4.0's drivers (dated early 2011) obsolete.
NVIDIA GeForce (discrete) Graphics Drivers: It's likely that the official NVIDIA drivers won't work on your NVIDIA-based Macs (though it's worth a try), so you will likely have to resort to a bit of driver modification to get the latest drivers to work. It sounds worse than it actually is. Simply head over to the LaptopVideo2Go forums and choose the latest GeForce driver series category.
These forums host literally all Nvidia drivers that are released through various channels (e.g., OEMs, developers, etc.). If you're getting any of these, watch out for the "MS WHQL Certificate" tag and read the forum comments carefully to avoid potentially buggy drivers. First, you need to click on "Download Driver", download the package and extract it. Then, right click on "INF Modified" and save the INF file under the "Display.Driver" directory found inside your driver folder.
That's it! This will remove all hardware checks and will allow you to install NVIDIA drivers on your Mac.
Broadcom Wi-Fi Drivers: The broadcom chip is present in most recent MacBooks, iMacs and Mac Minis. Station-Drivers.com has the latest drivers. Scroll down to the "Broadcom Wireless 802.11a/b/g/n controller" section and get the latest drivers for your OS.
Realtek HD Audio: The Realtek audio chipset is also very commonly found in Macs. Unfortunately, again, the installation requires you to do some tinkering: Go to Guru3D and download the latest Realtek HD Audio drivers. Make sure not to get the MSI installer, we need the extractable ZIP/EXE format, you'll see why. Download and extract the file.
Go to "Device Manager", double-click on "Sound, video and game controllers" and then "Realtek High Definition Audio". Go to the "Driver" tab, click "Update Driver" and point it to your downloaded directory. Hit "OK" to install these drivers.
If you don't follow these steps and just go with the regular installer, you'll hear no audio out of your speakers, it's likely one of those weird little Windows on a Mac issues.
