Currently Being ModeratedNov 15, 2009 12:21 AM (in response to McFlossy)Following mpuck972's solution of deleting the ATIKMDAG.SYS file worked for me. I got Windows 7 64-bit RC installed. I then installed the Boot Camp Drivers from the Snow Leopard CD that came with my iMac. Everything seemed to work fine. I had sound, full screen resolution, all the keyboard keys worked, and even had scrolling with the magic mouse!
However, after a few minutes of use the mouse and keyboard would hang, and I have to do a hard reset of the computer. Is this a bluetooth problem or is there some other issue? I have't tried it with a usb wired keyboard/mouse yet.iMac 27" Inte; Quad Core i5, Mac OS X (10.5.8)

Currently Being ModeratedJan 25, 2010 9:21 AM (in response to McFlossy)I also had this problem, and I wrote this step-by-step guide on how I solved it:
However, before that I also had another problem, namely that partition for windows could not be create by boot Camp. I got this message: “The disk cannot be partitioned because some files cannot be moved”. I also found a solution to that problem, which I wrote here:

Currently Being ModeratedFeb 5, 2010 12:35 PM (in response to joudbren)Yup. That's it. I connected the second monitor, did the last part of the install on it and as soon as the install was complete, Windows immediately downloaded an updated ATI driver and switched the video back to the 27" screen.
Thanks joudbren, you saved me some pain.

Currently Being ModeratedFeb 25, 2010 4:37 PM (in response to McFlossy)Hello,
This is my first post and I generally don't post in forums (dedicated lurker) so please forgive me being a neophyte on board/forum etiquette. That being said, I've have had this problem on a brand new imac and found this page on Apple's support site: [http://support.apple.com/kb/HT3986]
What really helped was this: [http://support.apple.com/kb/TS3173] which has the steps for creating a bootable usb drive with the required imac's drivers to complete the installation.
Hope this helps, it worked for me. My head still hurts from bagging it against the wall because of this issue.

Currently Being ModeratedFeb 25, 2010 5:17 PM (in response to McFlossy)*Proper MBRFAT USB drive formatting for WIndows 7 drivers.*
+I Followed the instructions at http://support.apple.com/kb/TS3173, and still got black-screen error installing Windows 7 on a late-2009 model iMac 27"+
My problem was that I was reformatting the drive from the Erase tab of DiskUtility, not the Partitions tab, you HAVE to use Partitions tab.
For step 6, Apple Support's senior technician ran me through the following successful process:
a. Select the USB drive from menu on left.
b. Click the Partitions Tab
c. Select Volume Scheme > 1 Partition
d. Select "Options…" button and choose Master Boot Record from the pop-up menu
e. Under Volume Information:
i. Name = MBRFAT (all caps)
ii. Format = MS-DOS (FAT)
f. Click apply then click partition, wiping the drive and reformatting it, then close DiskUtility
For step 7, AutoUnattend.xml and the drivers folder go in the root directory of the MBRFAT partition of the newly-formatted USB drive.
Hope this helps.late-2009 iMac 27", Mac OS X (10.6.2)
Currently Being ModeratedMar 8, 2010 9:39 AM (in response to McFlossy)For those of you still having problems finding the right file to delete, here is what worked for me. My computer specs are Imac 27" 3.06 4gb ram and ATI 4670 graphics card, this solution will not work for Nvidia card macs. I installed Win 7 x64 via bootcamp and got to the black screen, restarted and booted to the Win 7 x64 disc. Clicked on repair system and chose my Windows 7 installation, then I hit next and clicked on the icon to open command prompt. While in command prompt type in: "Del C:\Windows\System32\DriverStore\FileRepository\atiilhag.infamd64_neutral951c1812f542740a\atikmdag.sys" without the quotations. I found it to be case sensitive at least for me so just type it exactly as you see it here. Restart you computer and it should complete the installation.Imac 27" 3.06ghz 4gb ram ati 4670, Mac OS X (10.6.2)

So I just spent the past 5 hours trying to install Windows 7 via BootCamp on my new 27" iMac. It would get past the initial installation and then after the final reboot just before it runs off the hard drive and asks you for a serial number, the screen would go black and I couldn't do anything. So I found this solution here:
Except the instructions on that site are for an iMac with an NVIDIA Graphics Card. The 27" iMac has an ATI card. So at step 6 I deleted the file named: ATIKMDAG.SYS from the same directory.
Then clicked restart and was able to finish through the install process.
It seems as if for some reason Windows 7 installs some random NVIDIA graphics driver that the ATI card just cant handle. Once the install get to the point where it's turning on that driver, the iMac's display simply turns off because there is no card to run it.
The BootCamp driver that loads only give a max resolution of 1980 X 1440 so everything looks stretched. Installing the ATI drivers from ATI did no good.
There also seems to be an issue with the sound drivers, and the bluetooth usb host controler. There is no sound, and the mouse doesn't become active until everything is done loading.
Also be aware that only the keyboard will be active during the install so you will need a usb mouse unless your really good at navigating Windows with only a keyboard.
This solution worked for me, thanks!!27" iMac Late 2009, Mac OS X (10.6.3), i7 Intel, 16gb ram
Currently Being ModeratedMay 12, 2010 4:00 AM (in response to McFlossy)Connect an external monitor and complete the installation that way.
After you can install the bootcamp software and use your normal 27" display.

Currently Being ModeratedMay 14, 2010 2:44 PM (in response to joudbren)Joudbren!
That's amazing - I had tried to install twice (even placing the drivers onto the thumb drive) and had specifically unplugged my second monitor to install. I had been getting the black screen, but when I restarted in Win7 with the 2nd monitor plugged in there it was.
