Okay, Dr. Hurts RC3 installer worked, then I copied over 10.3 boot.
The thing I had to do was to set my USB Flash to be priority boot over HDD in bios.
Then it booted fine and installed fine too. I did not specify (" -v -x32 ") before the install. Is that bad?

Now, my next problem is about "Back on Leopard" step. I have two machines - old PPC iMac G5 and PC hackintosh (brand new) that I'm trying to install SL on. So what can I do to install Chameleon now onto the new hackintosh SL box?

Edit: I figured it out. Just used the flash drive to boot to Chameleon and then selected the new HDD with SL install. Got it to boot on its own. Now to get the video card working (GeForce EN9600GSO). Any good tutorials on how to get that working?

Another edit: Got my video card to work using Universal Installer using custom install. Want to tanks Sk1n for all the great help!
