Chameleon 2.0 does not work..? (for me)

[spiritonline]

HI all,

after a couple of days,long hours and pulling my hair, pretty much going insane I finally managed to install OSX 1.5.6 (retail) on my DELL XPS M1730 *hurray*

Now I'm attempting to get chameleon to work so I can dual boot it with my windows 7 (which was already installed before OSX.)

So I've downloaded chameleon 2.0 (installer) with windows and installed it on my mac but then when I reboot (without the 132 boot CD) it will boot straight into windows...
Can anybody tell me what I did wrong ?

specs:
(hardisk are now 2 seperate HD's one MBR-(windows 7) and one GUID -(mac install)
