Q: Drive permissions to no access for everyone

I set permissions on my drive as no access for everyone. To make it worse I applied to all sub folders. Now mac will not boot. Also cd drive does not work so that is not an option for booting. Any suggestions please - need help

    Which partition(s) of your HHD did you set No Access to?  For example, my 1TB hard disk has the following 3 volumes in my 3.6Ghz Intel Core i5 iMac:

    1.  (BSD Name:  disk0s1 with Capacity:    209.7 MB), 

    2.  (BSD Name:  disk0s2 with Capacity:    200 GB), and

    3.  (BSD Name:    disk0s3 with Capacity:    799.73 GB).

     

    Does the problem of not booting applies to just disk0s2 which is shown as the "Startup Disk" in my iMac?  I wonder if you would experience the same problem of not booting if you set No Access permission to disk0s3 which i named it as "Macintosh HD 2" to distinguish it from Macintosh HD?  (Macintosh HD being disk0s2)

    The first response from BDAqua worked for me. I was a little iffy about typing commands, but it worked and wasn't as scary as I thought it'd be. Thanks for posting!

     

    Start up  holding Command+S

    Let the code finish loading on it's own. It might hang for a second on certain lines before it completely stops loading so you can type.

    mount -uw /  (Press 'return')

    chown root /  (Press 'return')

    chmod 1775 /  (Press 'return')

    exit  (Press 'return')

     

    System will reboot on it's own. If this was done correctly you should come to the login screen and your system will function like normal again. Another post mentioned to copy and paste these commands onto a doc so you can see where to add necessary spaces between characters. That was a good suggestion also.
