Windows 7 64-bit on older machine not listed

Anyone succeeded to install Windows 7 (Professional) 64-Bit with Bootcamp on a Mac not in the list bellow?
That is, older than those:

These Macs can use 64-bit editions of Windows Vista and Windows 7:

MacBook Pro (13-inch, Mid 2009) and later
MacBook Pro (15-inch, Early 2008) and later
MacBook Pro (17-inch, Early 2008) and later
Mac Pro (Early 2008) and later
iMac (21.5 inch, Late 2009)
iMac (27-inch, Late 2009)
iMac (27-inch, Quad Core, Late 2009)
MacBook (13-inch, Late 2009) and later
Mac mini (Mid 2010)

I have a iMac 2.4 GHz early 2008 ( http://support.apple.com/kb/SP485), so not that old...

The processor supports 64-Bit :

With some computers you can use an authentic, 64-bit Microsoft Windows 7 Home Premium, Professional, or Ultimate disc

The DVD has to be reburned to get around booting W7 64-bit, which is done from Windows, so you would temporarily install on a VM.

"Support" hinges primarily on having EFI64 / UEFI 2.x

Just to be sure I understand:
- These older Intel macs have a BIOS that functions the same as the ones listed?
- If not, you need to take your Win 7 DVD and reburn it with the nuance settings explained on the post at jowie.com? The way the DVD is burned out of factory is incompatible with older macs?
- Only then can you reboot on the NTFS partition and install Win 7 ?

What do you mean by this:
EFI64 / UEFI 2.x

Doing this to check if the Mac has EFI64 seems helpful to check:

Here are my results after further digging online and from my own experience.

Here is the procedure:

1. Check whether your Mac has the 32-bit EFI or 64-bit EFI
http://www.ihackintosh.com/2009/08/snow-leopard-106-and-64-bit-what-you-need-to- know/

2. Create a Boot Camp (BC) partition for Windows 7 x64. Resize the partition size using the slider in the BC app. Follow the instruction, insert the Windows 7 disk and reboot.

3. This will load the PC partition which is FAT formatted for now. Choose the Boot Camp partition on which to install Win 7, but choose in the option to format that partition. It will automatically format it in NTFS. Otherwise, it will not install on that partition.

Note : A "OEM System Builder" Windows 7 64-bit Professional UPGRADE install without any issues what so ever. The upgrade disk is a full install. Read this for further information:
http://www.pcworld.com/article/174288/windows7_upgrade_madecheaper.html

4. Run windows, then insert the Snow Leopard disk. It will tell you your hardware cannot support x64 version. Do the following procedure to manually install the driver:

5. Then update Boot camp using Apple Software Update in Windows.

6. All hardware works fine except the sound. The sound only comes out of the internal speaker, even when headphone or speakers are plugged in the jack. Installing the Realtek High Definition Audio Codecs driver in order to fixe the problem. Shutdown and reboot to make it applicable. Try a second time if it still does not work:

That's it.

Hi Brun,

I have a mid 2008 3Ghz iMac which is telling me I have EFI64.

I have already bouught Windows 7 64 bit as I assumed this is what my iMac was, but have since read that only 'late 2009' iMacs are ok for 64bit.

Are you still running 64 on your non-listed Mac? Any issues? Would really like to hear as I need to decide whether to return it for the 32 bit version or to go with it.

Many thanks

Mark

Some links seem outdated. Please could you update the procedure on how to manually install the drivers.

I would like to install Windows 7 64 bits on my Mac Mini Late 2009 with Lion.

This particular Mini should be able to load Win7 x64.

Lion users must create their own driver CD/flash stick with Boot Camp 4.0 drivers, which is done by running Boot Camp Assistant and following the prompts therein.

If you are running a 64-bit Windows, your CD/flash stick should automatically detect such upon running Setup.exe from said CD/flash stick. You're either going to get the message that it isn't supported, or you will be able to proceed normally.
