Question: Hard Drive lock in the re-instal process
I checked many forum and I can't fund an answer to my problem.
I did a reset of my Mc Sierra. After been to "Disk Utility", "Erase"(first partition on the top). Then I went back to "macOS Utilities" Press "Reinstall macOS", agree to the therms.
The first time I been there I had two hard drive, one was could not select it, and the second one "OS X Base System" could not selecting it "This Disk is locked".
Following some forum steps, but i wasn't able to unlock it.
What can I do?
Thank you for your help!
iMac, macOS Sierra (10.12)
