MacBook Pro running 10.5+ Won't start up. Was running great, have not installed anything new for weeks and have not moved any files around. Searched and tried the following: I have reset PRAM, SMC, tested hardware with DVD (quick 3 min. hardware test came out good). I was able to press C with the DVD install disk in and get the install/reinstall options to come up, but have not done an archive and install just yet. (not sure this is what I should do) I could NOT boot from install DVD using option on start-up(as pax described above) I could NOT boot into safe mode??? I have a two month old super duper BU. However, I tried to boot from that superduper backup and it seems to boot up weird. One time I could get to the log-in screen but no futher, and another time I got into my main login, was able to view all the files, but the finder froze up and when I relaunched finder everything went away except fro my background desktop pic. NOW THE PORTABLE HARD DRIVE WITH MY SD BACKUP WON'T WORK!! My portable hard drive in partitioned. I have a super duper backup on one partition, and I just copied my main user folder to the other as a secondary backup plan. However I CAN'T ACCESS EITHER NOW EVEN ON ANOTHER COMPUTER!!! Unfortunately my time machine backup failed several weeks ago and I have not had time to trouble shoot that and resume the backups. (of course now I am forced to troubleshoot!) So what should I do next? Archive and install? other?
