Hello people, after I installed Snow Leopard on my wife's LG X120 she asked me to put back XP since OSX didn't work 100%.

For some reason the installation cd stops when I have to choose where to install Windows saying that there's no Hard Drive available.

Is this related to my previous installation of Snow Leopard (bootloader maybe) or something else?

Did someone try and success the "back to xp" process? Or is like a friend told me "Once you go mac, you can't go back"?

Thanks in advance
