I'm running a MBP with an SSD in what used to be the optical drive bay. I have a SL DMG installed to a flash drive but it's giving me some trouble on another Mac I've tried to install it on. Spinning twirly ball at reboot trouble. I could re-install the optical drive, but I was hoping maybe I can install over gigabit ethernet? I think I've read about this but I'm missing the correct search term I think. Help appreciated.
