Enable Storage on a single disc - I am new and confused

I’m so new at this I don’t even know if I’m asking the right question.

I put ZimaOS on my old HP Notebook circa 2015(?). It installed and I have access to the web UI via IP address. I’m tinkering, and would like to use the HP as my only storage. To do that I do the following:

Storage → Create Storage → Start

Enable → Format All

Format and Enable

Then I get this error message: unlinkat./// DATA: read-only file system

If I try to just Enable storage I just get a blank error message. See attached.

Am I doing this completely wrong? What step(s) am I missing? Do I need newer/ different hardware?

Thanks!
