    Make sure you have a big USB3 Flash drive and format it for OS X. Also use a cloning program like Carbon Copy Cloner and clone your current drive (on OS X a clone will be able to be a startup drive if "blessed") or install a clean version on the HFS+ Flash drive. On a Mac after that make one can either use System Preferences->Startup Disk or hold down the 'option/alt' key while first booting up and select the bootable external.

    For a Fresh install make sure you have a big speedy "pen drive" and then format that drive using /Applications/Utilities/Disk Utility for OS X. Then download/install OS X onto the drive (make sure you tell the installer to use that mounted HFS+ drive) and point it to that USB3 thumb drive.

    You will need a Mac at some point to use the App Store to obtain the installer DMG. Once you have obtained the installer, you can use TransMac on the Windows machine to make the installer key.
