I have just wiped my iMac, and something must have gone wrong in the process as i cant change the boot drive by holding down option key and when i go to install reinstall macOS through macOS utilities when i select the 500GB hard drive the main one it just says "Disk is locked". Can anyone help me with this issue?

In my case the problem was that i removed Paragon NTFS files and not uninstalled it properly. So installing and uninstalling it fixed the issue – Morteza Rastgoo– Morteza RastgooCommented Jan 12, 2020 at 7:37

I believe you followed the official guides and you tried to factory reset your Mac and you find yourself in this situation: the disk is locked and you cannot select it for re-installation
You already tried to partition the disk multiple times but it keeps erroring with the Error: -61
In this case you can try:
- Cmd+R : For the normal reinstall but the problem still persists
- Shift+Alt+Cmd+R : For the internet reinstall but the problem still persists
The solution for me was to restart the Mac just pushing Alt
In this case you will see this:
Arriving at this point you need to select not your MacintoshHD but the one on the right instead which is the image of your Mac.
Once selected you will have the chance to format MacintoshHD (this time the right way) and then, without rebooting, choosing to reinstall MacOS:
At this point you are good to go and you will see the actual MacintoshHD which you can select to reinstall:
