is it possible to install snwoleo on a PC without having a running mac os?

Hallo,

I have just found "how to"s that requires a working mac os. Unfortunatly I and nobody of my friends do not have anyone. So here is my question, if it is possible to install SL one this PC (look below) without having a running mac?

I have a:
HP dv7 with a i7-720QM Processor at 1.6GHz,
4GB DDR3 RAM,
1GB GeForce GT 230M Graphics and
2x 500GB SATA HDD

There is allready running a win 7 on it.
I have bought a mac retail (MC223D/A).
And I have tried to install it form booting empireEFI, but with no working results. After their were running a lot of comando lines in the background of empireefi, my notebook just reboots and nothing is done.
I have tried also to install on MBR and GUID partitions, with the same results.

Pleas help me somebody.

best regards
rudohl
