Mavericks failed to load. Apple sent replacement Snow Leopard but disc won't run...just grey Apple
Downloaded Mavericks and it won't run and install on Mac (11/11) which had Snow Leopard, 10.6.8. Says bad HD, but HD is and was always fine.
Now trying to reinstall and wipe HD with Snow Leopard via disc but it will not load.
I have no controls, just a grey apple on screen.
iMac, OS X Mavericks (10.9.1), New Mav won't recognize HD,
