Mavericks install=grey screen of death
While installing Mavericks my computer restarted to a grey screen and never went any further. After 2 hours I rebooted and still the same. I tried holding the option key to boot off an exterior backup but no screen. Safe mode and recovery mode also brought back the grey screen.
