    Bootcamp Win7 64bit and iMac 27" 2010
    Hi all,

    I plan to install my version of windows 7 64bit on my new iMac 27, i7 Late 2010. I originally read that the 64bit version can be installed on later model iMac's.

    However, I just came across this site from Apple and it doesn't specify that 64bit win7 can go onto that model iMac, only the 2009 model.
    Boot Camp: Macs that work with 64-bit editions of Microsoft Windows Vista and Windows 7

    Is this true? Has anyone installed 64bit windows on the late 2010 iMac 27 i7 model?

    If I have to install the 32bit, would that have any effect on the mac OSX side of things which run in 64bit?

    Actually, another question... does anyone know if the late 2010 imac27 i7 have the black screen issue when installing bootcamp, or has this been resolved?

    Moved to appropriate forum.

    There is no reason to believe that Windows 7 64 bit can not be installed on the 2010 iMacs. If it's a question of video drivers, Apple will have addressed that with a Boot Camp update or include them on the Snow Leopard DVD set for the 2010 iMacs. Some drivers may have to be downloaded from their respective hardware providers like ATI.

    And no, if you install Windows 7 32 bit it will not have any impact on anything that is installed on the OS X side. Remember, this is a dual boot which means that Windows 7 is running separately from OS X.

    You also mentioned the black screen problem.... As far as I know it's not an issue with the new iMac. You might want to do some searching to verify all of this just in case.

    I have installed Windows 7 64bit using bootcamp on the iMac 27" i7 which I received from the Apple Store in October 2010.

    No problems encountered and runs extremely well. Web browsing on 27" screen is a joy.

    No black screen you reference encountered

    Only problem I encountered was when I subsequently tried tried to create a 2nd Fat32 partition between my Macintosh HD partition and the Windows 7. What happens is you are unable to boot into anything Windows 7 or Osx. It was then I learn how little I knew about the iMac boot process, when I really needed to. After a bit of surfing via my iPhone found the option button to hold down whilst booting and boot into Osx. I then deleted the additional partition and all well.
