I believe he is trying to wipe tiger and simply run windows on a mac (without the mac).
I also believe he is trying to avoid boot camp and he wants to boot directly into windows.
Just trying to clear things up...
Im not sure if this is possible...didnt find anything on an extremely brief search.
I dont have experience wit hintel macs though
Only PPC
EDIT: Maybe you could return it...or sell it. PCs are generally cheaper to build than to buy a mac.
