Hi, I had to change a failed hard disk, now my main hard disk is protected, when I try to add my name I get the message that the operation can't be completed and gives the error code 8076.I'm the only user of the computer and the system, when I click to add a new user shows two choices, Administrators and my name, but both fail to be added. Using Disk Utility my main disk has two partition one is called Sierra with my operating System, the other small one called System Reset (104.9 MB SATA Internal Physical Volume Mac OS Extended (Journaled), listed as disk1s1, there is no option of deleting this partition, and I don't know if this is the cause of why I can't modify my system disk, on system preferences I can see my name as Admin but the option Allow user to administer this computer is enabled but greyed out.
