Hello everyone.Yesterday i tried to install iatkos but i messed up.So i have preinstalled windows 7 in the HDD and i want to install leopard (iatkos v7)

My specs are:
Intel core 2 duo E4600 (2.40 GHZ)
2GB RAM
Motherboard is ASUS P5KPL-AM EPU (sound VT1708)
Network card RTL 8139d (PCI not onboard)
Geforce 8600GTS
160GB HDD (7 installed in) and 250GB(which is partionned to 220GB and 30)

In 30GB partition i want to install leopard.
Will chameleon bootloader work to boot to win7 and mac?Will the version of iatkos work for me?
