No Disk shown when trying to reinstall macOS after erasing it
I'm trying to reinstall my macOS after erasing my computer, but there is no disk listed to choose from. I've researched what to do from here, but I'm stuck.
How I got to this point... I followed the directions on erasing my iMac (2019): I went into Disk Utility, erased Macintosh HD, APFS, “erase volume group” as described in instructions I found. Then tried to Reinstall MacOS and this is where I am now, with no options on the list in which to place the OS.
When I go to Disk Utility now, and select “show all devices,” my screen displays in the upper left “Fusion Drive” with sub files of “Container disk3” and another sub file of “Update.”
Below that, there is another main file called “Apple Disk Image” with an eject icon option next to it. That file has a sub file called “macOS Base System.”
I’m hesitant to delete any of these two main files to see is this helps, in case those files are important to the operation of my computer. Please provide guidance.
iMac 27″, macOS 14.0
