How do you recover a demounted drive without reinstalling a mac

Hi


I accidentally set the everyone permissions on the Mac HD to no access and the drive demounted. Is there any way to recover it without losing the data?

MacBook Pro with Retina display, iOS 7.0.6

You have LOCK everyone out, even the System. No easy way to recover that I know of. The only option might be reinstalling OS X on and external drive and boot the system from that external and see if you can change the permissions back.


Or in single user mode with some terminal command to Reset all permission.


Look through these link.
