How to Tri-Boot Operating Systems
This goes for iDeneb v1.3 10.5.5 also.

Hello, and Welcome to my first Tutorial. If you have any questions, PM me.
Step 1 - Creating Partitions and Installing the First Operating System.
First off, you are going to need 3 things for this Tri-Boot.
1. 3x Operating Systems. One of them being Windows.
2. EasyBCD (Windows) EasyBCD Download
In this tutorial, I am going to start out with my version of Macintosh OS X.
In the Mac OS X Installation, you are going to want to go to the Menu bar > Utilities > Disk Utility. From there, we will create 3 Partitions. (You can also do this with Gparted if you are not using Mac OS X Leopard).
One of the partitions we will make is a Mac OS X readable format. That being Mac OS X Extended (Journaled), naming it Macintosh HD, The second partition we will make is FAT32, naming it WINDOWS. The third we will also make FAT32, naming it LINUX.
This is an example of how you format your drive.

Now that you have made your Partition, you should be ready to install the OS. Once the installation is done, restart and follow up on the Mac OS X setup. This is very crucial.
Step 2 - Installing the Second Operating System.
Now that my Macintosh OS X Installation is finished, I am now ready to install the second operating system. This Operating System is Ubuntu 9.04. You can find out more info on Ubuntu here: Ubuntu Home Page | Ubuntu
When installing Ubuntu, you will go through the normal. Time, Keyboard setup, etc etc. When you get to the partitioner, this is where you need to pay attention. Writing over the wrong drive can be a pain, and it can get nasty with installations. So keep your eyes on the screen and not on the pictures.
When you get to the partition manager, you will notice a couple of options. Select to manually select the partition. This is so you can see your partition labeled "LINUX". When you find that partition, delete it. You now know which one it is. Now select the nameless partition, right click, and edit. Here you will need to do a couple of things.
Now that you have set that up, you will be able to Install Ubuntu. After you restart, the GRUB loader should pop up asking if you want to boot linux or Mac OS X.
FORMAT - Ext3
and set your boot to go to "/"
Step 3 - Installing Windows and Finishing Up
Now that your other 2 Operating Systems are installed, you now need to restart, and install Windows. I am using Windows Vista Home Premium for this last part of the installation because I can install the tool that I need on this Operating System.
First install Windows, and follow up through the installation, remember to install on the WINDOWS partition. After you have your Operating System set up. It will be the only one other then the GRUB loader that pops up. Why you ask? Windows has a funny way of over writing bootloaders. So this is where EasyBCD comes in handy. Instead of trying to make your own Boot Configuration Diagnostic, this program will do it for you. You can download it >Here<.
Here is an example of how to use it.
First you will need to go to the "Add/Remove Entries". In there, you will find a variety of Operating Systems you can add to that list. Find the Operating System you run, and add it to the list, then Save. If you don't save it, it does nothing!
After you have saved your boot configuration, restart your PC! First the GRUB should boot up, select Windows, and then you have 2 more options to select an OS. 1 being Windows Vista and the other being Mac OS X!
I hope this tutorial helps, because I spent 30 mins writing it. If you have ANY questions, PM me.
