I'm planning on reinstalling Mavericks from scratch to solve a performance issue. I tested the USB drive I made today by plugging into my Mac, rebooting while holding down "shift". It recognizes the USB drive as being a bootable volume, but it also showed a restore partition on my Mac. When I reinstall OSX, will it create a new restore partition by default, or do I have to tell it to? Is there an advantage to not doing it, if I have the choice?
