We don't support iCrap here and I would not recommend you use Windows either. If you have no existing Mac or Hack to start from, install SL with NawCom ModCD. Plenty of detailed tutos on this forum, just do a search.
Once you have that SL installation in place, you can build your myHack USB installer for SL, Lion, possibly ML and Mav if you have the right D630 model.
