Hi there!
From macOS Recovery, try to erase the main internal disk (APPLE HDD ST3000DM001 Media), create a volume, then reinstall macOS to it:
1- In Disk Utility, select the main hard disk entry and click erase.
2- In the pop-up window, be sure to choose the correct format and scheme:
3- Click erase, and quit Disk Utility.
4- After erasing your startup disk, reinstall macOS from macOS Recovery: How to reinstall macOS - Apple Support.
Hope this helps! Let us know if you have any questions.
