Dual boot windows 7 and Mac OS X

I am willing to either dual boot windows 7 and mac os x on a computer i just built with i7 processor or just install mac os x on that computer. I have download iatkos v1.0 and snow leopold. the computer can boot on either one. My problem is after I selected the language I was asked where I wanted to install the program,I was stuck there. Can any one help me please?

Any help appreciated.

I didn't find the right solution from the Internet.
