Hard Drive lock in the re-instal process

Hi there,

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!

You said you did a "reset". That usually means erasing the hard drive and reinstalling from scratch, is that what you're trying to do? To erase the hard drive you'll need to boot into recovery by holding Command-R at start up and run Disk Utility from recovery. How to reinstall macOS - Apple Support

Lose your old windows habits, Mac OS doesn't need the same kind of maintenance that windows does. Keep it up to date, don't use third party maintenance or cleaning utilities, don't use anti virus software or any other kind of protection and above all use common sense computing practices and you'll be fine.

Well I never install any anti virus or any thing like that, and I never reboot the computer in 4 years. And I was following step for doing a manufactory reset. I am going to try the link you sent me and I come back to you.

OS X Base system is the recovery partition, it isn't available for installation. If you can't select the hdd there might be something wrong with it. Why did you erase it to negin with?

My computer was getting very slow, I have it for few years, and never really do anything on it. I usually do that with my PC every years.
