I have successfully triple booted a computer that gpt table looks like this.

EFI 2000MB
MAC OSX 100GB
Windows 7 50GB
Vista 150GB


This was originally a Bootcamp computer running 150GB Mac, 150 GB Vista

Things you need:
NTFS-3g
Macfuse for NTFS 3g
rEFIt

Instructions are to

1. Install Boot Camp Windows Vista to the size you need
2. Install rEFIt
3. Use diskutil in OSX to resize OSX partition
4. Create New partition using the unused OSX space and format using NTFS-3g as MSDos
5. Now Run Windows 7 Install DVD and install to the MSdos partition formatting to NTFS first within install.

You should now be able to boot Vista and Vista from the Vista icon in rEFIt, but you can do better

Follow these instructions:(While in Windows 7) These instructions from http://www.thaivisa.com/forum/Install-Windows-7-Windows-Vista-t232522.html

1. Copy the bootmgr and boot folders nested inside the copied folder (i.e. \Windows7) to root directory of system boot drive, typically C:\.
Note: For Windows Vista, users may need to use this step: Copy the bootmgr folder from E:\Windows7 to C:\ root directory, copy E:\Windows7\boot\boot.sdi file to same folder in C:\boot folder, and then copy bootsect.exe from the E:\Windows7\boot\ folder to C:\ drive.

Note: boot folder in system boot drive is hidden system folder.

5. Create a new folder named sources under the C:\ root folder.

6. Copy the boot.win file inside \Windows7\sources folder to the source folder created in the system boot drive, normally C:\.

7. Open a command prompt as administrator.

8. Run the following command (change the C to your drive path letter if applicable):
C:\boot\bootsect.exe /nt60 C:

For Windows Vista users who copied bootsect.exe to C:\ root folder, use the following command instead:

C:\bootsect.exe /nt60 C:

A successful message is the command completes successfully.
10. Restart the computer.

11. After booting up, the system will start the corresponding Windows installation process. Select the applicable language to install, time and currency format (regional settings locale) and keyboard or input method in the installation wizard dialog.

12. On the next screen, user will be presented with option to Install Windows. DO NOT press on Install Windows button, instead, click on "Repair Startup" link on the bottom left corner.

Reboot

You can now triple boot OSX, Windows 7, Vista

    Great walkthrough
    How is Windows 7 running? Does it have better fan control and/or access to speedstep (because of the efi support)?
    I'm running Vista but am very frustrated by the battery life and enormous heat...

    Amazing. Thank god for this!!

    I've been searching for DAYS!
  • CoolMe Level 1 (0 points)
    Just checking, we do not use the boot camp assistant to create the vista partition?
  • Keith A. Level 1 (20 points)
    Will this work with XP (instead of Vista) as well?
  • harrisharris Level 1 (45 points)
    You can leave the Vista partition bootcamped and not touch it. You can't resize the Bootcamp partition anyway. I did not use bootcamp to make the Windows 7 partition. If you already have Vista with Bootcamp you can leave it alone but you do not have to format the drive and redo it ; however, you may want to backup just in case.

    I've followed what you've said up until the resize the mac os X partition.

    I've installed vista NOT using bootcamp - Just installing it on the partition, I then resized and I have a partition called seven.

    See screenshot, do I just install seven on that partition now?

    Has anyone else sucessfully finished this yet?
  • CoolMe Level 1 (0 points)
    Nope. I installed windows 7, it restarted during the installation. I choose the partition with windows 7, it then said

    Bootmgr missing.
    Ctrl - Alt - Delete to restart.

    So I removed the partition and will wait until ive seeked help!
  • harrisharris Level 1 (45 points)
    Did you also have a Vista partition? You boot using the other windows partition either XP or Vista icon . You then follow the other instructions.
  • Keith A. Level 1 (20 points)
    It lives! (I'm on it now!)

    I followed the steps up until I was supposed to copy the bootmgr, and then just installed Windows 7 in the blank space (mostly out of laziness). It works fine! As long as I boot choose Windows from rEFIt I get the options in the Windows start-up of "Windows 7" or "Older version of Windows", and I can choose from there.

    By the way, NTFS-3g, Macfuse for NTFS 3g, and rEFIt are awesome tools regardless of setting up a triple-boot scenario.

    Now to consult the forums about my missing sound...

    BTW, after installing the boot camp drivers, itunes, quicktime, firefox, and avira antivir, I have less than 500 MB of my 12 GB parition left. 12 GB is just big enough for a look-and-feel of Windows 7.


    I do have one last question in this forum: If I had followed the rest of the instructions, would all 3 of my boot options (OSX, Windows XP, and Windows 7) shown up in rEFIt? If so, when I get the time I will follow those instructions...

    Thanks again for your help!

    Damnit, I just missed the cut-off for editting my last message. Anyway EDIT: Scratch that, XP only BEGINS to load. It crashes every time at the end of the loading bar, regardless of settings or safe mode. I'll re-post when this actually works...
  • CoolMe Level 1 (0 points)
    So your saying, install seven like I did, but when it restarts and I choose the 'Seven' partition, I should actually choose the Vista partition and there should be a boot menu listing seven and vista?
  • Keith A. Level 1 (20 points)
    Will following these directions give the give me all 3 of my boot options (OSX, Windows XP, and Windows 7) when I boot to rEFIt, or just OSX and Windows and I inside windows I choose my Windows version?
  • CoolMe Level 1 (0 points)
    Just like to clear up everything, I've got it working and this is how.

    Follow the instructions up till the bit where you resize mac OSX.

    Create a windows 7 partition, leaving at LEAST 200mb unpartitioned space (I left 6GB but oh well)

    Install 7 on your partition, and then when you reboot during installstion there SHOULD only be 2 boot options - Mac or the (Vista) partition, when you go into this, the boot manager has picked up seven and put them in a nice menu

    Hey prestro!
