Triple Booting on a Dell Studio 1747

[Silverguy]

Hello! I am somewhat new to the OSx86 scene, so please excuse my newbieness. I have been running OSX 10.6.4 in Virtualbox and like it, so I would like to set it up as a dedicated OS on my machine. However I am unwilling (for various reasons) to give up Windows 7 or Ubuntu. An *ideal* option would be a tri-boot. However upon looking around I see nothing on actually performing a Triple boot (as I said, I'm new so perhaps I just dont know where to look) I would like to leave the Windows partition in tact and untouched (beyond resizing, I'm going to have to make it smaller). I am willing to somewhat sacrifice with my Ubuntu partition, but I'd prefer for it to remain usable.

 

 

Tech Specs:

Dell Studio 1747

Screen size: 17 inches (1600x900)

RAM:4 GB DDR3

CPU: Intel Core i7 Q 720 @ 1.6ghz

Graphics Card: ATI Mobility Radeon HD 4650

Motherboard: Dell 0J509P

Bios: Dell A02 10/16/09

 

 

Current Partitions:

Windows: 401.07 GB NTFS (Willing to downsize)

Ubuntu:28.72 GB

OSSHARED:19.99 GB FAT 32 (I use this for things I want accessible by both OSes, but on neither of their drives. Just an independent partion I created. Willing to Re-Allocate for OSX)

Recovery:14.65 GB NTFS (System Came with it, Not touching it for obvious reasons)

 

Disk Size 500 GB

 

(Disk Manager can put it better than I can)

 

 

Right Now My Bootloader is Grub, when I select Windows it then loads the Windows loader, then finally it loads windows.

 

 

So, any help to accomplishing this would be much appreciated. I understand that this will be a complex project, but I think I can handle it. (Although those are famous last words) Straight off I would like to know how likely it is that I will seriously break my computer doing this?

 

Thanks in advance,

Silverguy
