Hi someone can help me? I have a little problem with running Mac OSX Leopard on my pc.

I succesfully installed iAtkos v5i on a new partition (Mac OSX journaled extended)
But after installation I can't boot into Leopard.
I've tried to boot into Leopard using the iAtkos dvd. command -s but all what happens is that the computer just restarts.
second I try dual boot using Easybcd 1.7
I restart computer and boot in Leopard. I get the grey screen and it stay forever.

What can the problem be?
