    So i can get a boot working fine for the three os's. so my next step is how do i get a shared data partition. i can get it so OSX and Ubuntu see it, but w7 won't.

    1 - EFI
    2 - OSX
    3 - Ubuntu
    4 - W7
    5 - Data

    any idea how i should rearrange this to make a shared data partition work?

    hi guys,

    i got it working after countless trial and error formats because the online information is so sketch.

    i found partitioning this way works

    Initial setup for win7/vista:
    1. HFS+ (OSX)
    2. FAT32 (Data/Storage/Shared)
    3. FAT32/NTFS (Windows 7 or Vista)
    4. FAT32 (Linux)

    this will make your MBR look like:
    1. EFI Protective
    2. HFS+
    3. FAT32
    4. FAT32

    and your gpt look like
    1. EFI Protective
    2. HFS+
    3. Microsoft Basic Data
    4. Microsoft Basic Data
    5. Microsoft Basic Data

    then install (in this order) OSX to the OSX Drive, Windows to the Windows drive, and Linux on the linux drive *with the bootloader on the data drive*
