So as many of you know I have G5 dual 2.0. I am looking to put Leopard onto it tonight as I finally got a good SATA II hard drive so this thing should be ready to go. I insert my disc and it keeps spitting the disc out, so I thought I had a faulty .dmg file written on the disc. Wrong... I pull the drive out and it's a DVR 107PD. After a little more research it turns out that this drive is not a Dual Layer by any means. It's just a DVD reader and writer, AKA useless 10 year old piece of technology right now. So what I am wondering is if there is any other way to do this. I don't believe I can boot from USB, can I boot from a partition on the hard drive and later delete this partition? Also, I don't have access to a macbook of any means right now so I don't have access to disc manager or whatever. Can I write this .dmg on my Windows 8 or Windows 7 machines onto a USB or hard drive to make this work? I look forward to everyone's responses regarding this question. Thanks!
