Thanks for your help Flip . What you've added is really what i'm looking for. Now I can create a USB drive to install. But where's the BootCD? The instruction from man_of_the_oak is good but it is for post-install configuration. What I need is how to install it. I've read and look around this topic and other forum but there too much information and I don't know where to start and how to start correctly. I hope you can state some basic step I will need to follow to get the right direction.
As I said before, I'm using the laptop for work with full of software, document, project and a lot lot configuration I've made to installed software. It's really frustrating to reformat the hard drive. I can backup data file but can't sure that Windows backup image will restore correctly after reformat. So anyway I can install Leopard to MBR partition?
