Ok I installed it sucessfully I think at least thats what the installer said.
When I reboot my laptop I see the leopard boot loader.
But then it gets stuck on that grap logo screen again.
So did the diagnostic mode and it just keeps repeating waiting for root device.
Again I'm using a laptop.

I set the disks up MBR and I installed the MBR Bootloader also.
So now It just keeps saying waiting for root device.

Thanks Again Guys!
