Error Checking Storage Configuration

I am new to Linux and wanting to install Rocky Linux 9.2 on my iMac 2019:

Spec: Intel 8xCorei9, 1TB SSD drive, 128GB RAM, Radeon Pro Vega 48 8GB

I have wiped my drive clean, however I am not sure what method to use to erase the drive using MacOS disk utility APFS.

When I get to the installation screen, depending on how I have formatted the drive, Rocky Linux only detects around 1GB free each time.

When I select Automatic, Delete All and Reclaim all space, it still says I only have around 1GB free. I then receive the error message Error Checking Storage Configuration.

Is there something I am doing wrong here?

Any ideas?

I think I’ve solved the problem. I clicked Full Disk Summary and Boot Loader and removed the selected disk from the list.
Then went back through automatic partitioning and it seems to have worked.

OK, it looks as though by deleting the entry, it does not create a boot loader, so I’m back to same issue.

I did go into error message details:

Resource to create this format macefi is unavailable

Any suggestions please.
