Can't reinstall OS X - "This disk is locked" [solved]

I'm writing this as I search for it and found solutions and none of them worked and I noticed I wasn't the only one.

Easy solution is hold down command + R and get into disk utility, select the main HD and select File > "Enable journaling" but if you are like me, it was greyed out. What the issue is, you are trying to modify the drive you are currently working on which it doesn't like. You need to create a USB flash installer, then reformate the drive then reinstall. The steps are below

Step 1 (i found step 1 at https://lifehacker.com/how-to-make-a-bootable-macos-sierra-usb-flash-drive-17868 53248:

The easiest way to create a USB flash installer is with the free program, Disk Creator.

1. Download the macOS Sierra installer and Disk Creator.
2. Insert an 8GB (or larger) flash drive. If you have any other data on that flash drive, back it up now, because the installer will delete everything on it.
3. Open Disc Creator and click the “Select the OS X Installer” button.
4. Find the Sierra installer file. This is should be located in your Applications folder.
5. Select your flash drive from the drop-down menu.
6. Click “Create Installer.”
7. When it’s done, insert your USB drive into any Mac, then launch the installer by holding down the Option key

Step 2 (now that you are booted on a the USB stick and not the main HD):

1. Once it loads, go into Disk Utilities and Erase the main drive and select the journaling formate style.
2. Then choose to reinstall the OS and the disk will not be greyed out this time.
