Did a software update (not sure if that is the culprit) restarted, and now computer only boots into the setup assistant screen. Even after I fill in the info is goes right back to the setup assistant. Tried rebooting to safe mode, login appears and am directed back to the setup assistant after logging in. Did disk repair and permission repair from the install disk with same results. What else are my options before I just wipe out the HD and do a clean install?... Anyone else with this?
