Hello everyone! Im new here so please bear with me.

Tried installing Winxp and Kalyway 10.5.1 Leopard using this installation guide. I successfully installed the winxp and the installation of the mac os was successful as well. I used the Gparted Live software also. The problem was when i tried to boot the mac os for the first time, it get stuck to the apple logo (including the loading logo, the one spinning around). Any ideas on how to fix this? TIA!
