Permissions Errors with Macintosh HD

Hey guys,

I'm running a Macbook Pro (Samsung Evo 256 GB SSD) with Mac OS X 10.10.

I had a problem with an Adobe product installation, so I followed their instructions to enable root user. Additionally, I deleted a directory domain under Users and Groups that was causing my account to find a lost server upon login and would at times hang my account. Upon reboot, my username/password combination would not work.

I booted into recovery mode (my username being System Administrator (root)) to try to do a TimeMachine restore but an error prevents me from completing the restoration. I then tried to reinstall OS X via system utilities, and it's telling me that Macintosh HD (my internal drive) is locked. I then tried to use disk utility to either enable journaling or repair permissions, but all those options are grayed out. I do not see an unlock drive option anywhere in recovery mode. I tried to reset me password via the resetpassword interface, but I do not see any volumes/options to reset a password for any user. Reset home folder permissions and ACLs is grayed out.

I then tried to use the following command to reset my permissions in single-user mode:

sudo chmod 1777 "relevant volumes"

The sudo command shot pack an error saying "command not found". I tried to chmod without sudo, and an error shot back that the disk is write locked.

I was reading that this could be due to a wrong path, so the echo $PATH output is the following:

/usr/bin:/bin:/usr/sbin:/sbin

So, I'm pretty much stuck at the moment. I have all necessary data backed up via TimeMachine on an external (no clones unfortunately). I'd just like to reinstall OS X or do something to resolve the situation.

Cheers,

Michael
