    Mac Pro 10.6.3
    Boot Camp Assistant 3.0.1
    Windows 7 Home Premium (64 bit version)

    After trying to install Windows 7 on a 32 GB partition using Boot Camp Assistant, I received an error message saying that Windows 7 needs to be installed on a partition formatted as NTFS.

    How do I format the Windows 7 partition as NTFS?

    The steps outlined by Boot Camp Assistant don't seem to include an option
    to format a partition as NTFS.

    Thanks for any tips.

    You have to use the Windows installation disc. Insert the disc and let it start up from the disc. Then there will be an option to format the selected partition to NTFS.

    By the way, with NTFS, you don't need to use 32 GB partitions. You can set it to anything.

    i did lots of looking and found lots of discussions with no solutions. i had a problem with the bootcamp (and macos) not showing up in the startup disk control panel and bootcamp setup assistant yelling at me. sure, i could hold down the option key at startup and choose mac or windows, or use BootChamp ( to boot into windows. the problem was with the Partition Map Scheme for the entire disk. it needs to be "GUID Partition Table" rather than MBR (or Apple). i didnt want to reformat the entire drive to fix the problem and then restore the mac and windows data, so i used iPartition ( it converted the partition scheme and everything now works as it should.
