[Help] Dualbooting HP Mini 110

[neonn]

First off, I have my HP Mini ready and of course have Windows 7 pre-installed, having that said, I want to create a dualboot system though I do not want to delete my current install/partition of windows 7. I want to base my install off of this: http://osxhpmini.info/multi-booting-guide/ though I think this is for a starting the system on a completely new slate. correct me if im wrong.

 

Any help would be appreciated.

 

Thanks.
