    Successful setup of OS X Lion + Bootcamp Windows 7 Ultimate + Data Partition

    Ok, so after many, many hours I think I've finally figured out how to successfully install Mac OS X Lion with Windows 7 on a Bootcamp partition AND an 3rd data partition. Here is a screenshot of my setup on my 13" MacBook Pro:


    As you can see, I have my internal 500GB hard drive partitioned the following way:

    120GB - OS X Lion (system and apps)
    316GB - workspace partition (user files, projects)
    64GB - Bootcamp Windows 7 Ultimate

    To make this work, I started with the standard procedure of installing OS X Lion on a single Mac OS Ext (journ) partition and using Bootcamp Assistant to build the Bootcamp partition for Windows.

    Then I did 2 key things:

    1. Before installing Windows on the Bootcamp partition, I first went back to Disk Utility, shrunk the OS X Lion partition, and inserted a 3rd partition Workspace_HD for all my user files. Then I restarted and installed Windows 7.

    2. After Win 7 Ultimate, the Bootcamp drivers and Office 2010 are installed and activated, I DID NOT make any changes to any partitions. I can put whatever I want on any partition, but I CAN NOT shrink, resize, delete, create, or modify any partition. Any change to the partition tables after Windows is installed will BREAK the Bootcamp partition.

    I went thru 3 broken installs of Bootcamp/Win7 to figure this out. Again, the key to this working is creating your extra partitions AFTER you make the Bootcamp partition but BEFORE you install Windows.

    I will rebuild my system for a 5th time to fully document the process with screenshots, but this time with 5 partitions: OS X Lion startup, Workspace, custom 20GB OS X Lion recovery partition, 30GB FAT32 shared Mac/Win data partition, and a Bootcamp partition with Windows 7 Ultimate.

    Until then, here is a quick step by step of what I did:

    - Install OS X Lion on a single partition hard drive.
    - Run Bootcamp Assistant.
    - Download drivers for Mac and burn to CD.
    - Make 60GB Bootcamp partition for Windows.
    - When prompted for install disc, STOP installation and quit Bootcamp.
    - Launch Disk Utility. Look at the 2 partitions.
    - Shrink Mac OS X partition to 100GB.
    - Click on + to create a 3rd partition in free space.
    - Split that partition into however many other partitions you want.
    - Quit Disk Utility.
    - Insert Windows 7 installer DVD and restart Mac.
    - After the startup chime, hold down OPTION key.
    - Wait a while until the Windows 7 DVD appears and select it.
    - Mac should start up from DVD. Start installing Windows 7.
    - Continue until finished. DO NOT connect to internet.
    - Load Bootcamp drivers CD that you burned and install.
    - When finished, restart and log into Windows 7.
    - Continue installing your applications. Do activations.
    - When finished, restart, holding down the OPTION key.
    - You should now see your OS X Lion and Win 7 partitions.

    OK, hope this works for you!! Good Luck!! ;-)

    Or you could use Parallels to run Windows in a VM and share a home directory... :D
