Need help on os X 10.6/10.5 hackintosh

I first tried to install Leopard with iDeneb since it should just be a simple dvd install. Except, on the only pc i had that got it to run without the « Still waiting for host device » error, it throws a « could not read disk » (or something along those lines) error when starting the install.
So, i looked for another method and found the iBoot + retail snow leopard dvd method.
Thing is, i have a limited supply of blank CDs and DVDs and can’t just burn images like that (plus i don’t have any dvds large enough for the snow leopard image). So, only way i could boot iBoot without a cd was using ventoy, but then i had no way to get it to launch the snow leopard installer. So, i’m out of ideas, anything i can do to install leopard/snow leopard ?
