Not able to partition my 1.0 TB internal HDD back to normal.

Recently I had 550 GB of my HDD partitioned for windows through bootcamp. It all worked out well until I thought it was time for an upgrade. I went to my Disk Utility application and deleted the windows partition, and instead of the mac OS taking up the space, it was just an empty APFS container that I couldn't delete. I opened bootcamp and made another partition on top of my mac partition and windows did not install. I deleted the partition again and it was just an empty container. I reached the point where I don't mind formatting my computer as long as I get my 1 TB mac OS back.

A BCA-created partition should not be deleted by Disk Utility and vice-a-versa, unless there are very specific issues being addressed. The recommended method is documented in Remove Windows from your Mac using Boot Camp - Apple Support.


Can you post the output of


diskutil list

diskutil apfs list


from macOS Terminal?

You still have the two same containers, so nothing changed. El Capitan will not recognize APFS.


Does Local Recovery work? If it does not, then Leave your internal disk as is.


Use How to reinstall macOS from macOS Recovery - Apple Support and install macOS Mojave on an external disk (32GB or larger, USB3 is preferred over USB2 for speed). If you are offered El Capitan, install it on the external disk and upgrade it to Mojave. Till you get to Mojave, do not manipulate the internal disk.
