My computer now starts in safe boot mode always and after that my password is declined. I recently upgraded to Mac OS X 10.7.5 from Mac OS X 10.7. The last software I ran before noticing this problem was ' a Audacity'. I have tried to verify permissions but my hard disk is not mounted. It is greyed out and the verify permission tab is greyed out too. Pls any help will be appreciated.Computer won't start

Have you tried starting up holding command + r keys, or command + option + r?
If it starts that way, then go to Utilities > First Aid and run that.
If you have no recovery volume then startup from another disk or from the discs your Mac shipped with
Thanks for commenting. I ran disk utility and the error message I get says ' incorrect number of thread records'. What does that mean? The computer will actually boot in safe mode and get to the screen where I am to put in my password, but when I put in my password it flickers and then nothing happens. I put in my password again and nothing still happens. Will appreciate any help from this forum.
My iMac with Mac OS X 10.7 Lion did not ship with any disc!
You can follow an apple article https : // support.apple.com/en-in/ht204267
Back up everything now, it appears you may have a problem that disk utility cannot fix. Try running Disk Utility several time until it reports that it is fixed, or still fails. If it continues to fail you can try re-formatting and reinstalling OS X. If that fails bring it in to Apple for repair.
