iMac 2017 failing to start

Hi,


Our 2017 27inch iMac is failing to start. Upon turning on all I get is a black screen with 🚫. When trying to reinstall the operating system it does not give me any hard drives to select. In disk utility I get the below options (please see photos). I believe my only option left is to use recovery software to back up the data and erase and reinstall the operating system?
