So, I used mechdrew's guide on installing without a Mac. Was having trouble getting the Leopard ISO/Image to a drive and wound up using TransMac, then formatted the drive to HFS+ and wrote Image to that drive. I know it's a good idea to save the USB Flash Installer, at least that's what I've kind of gathered. Thing is, I used my external 500gb drive due to convenience, it was also speedier than my other choices. Obviously I don't want to waste this drive to be only for the installer, so what do I do? Right now it's exactly the same as an OS X Install DVD, it's even showing up like that in Finder. So, any tips?
