[PROBLEM] SSD Media / System Partition Issues

[japumpy]

Quick report back.

Disk Utility in Mac OS states that there is one partition of around 231MB of which around 32MB is used by the system. 
There doesn't appear to be any other partition as reported by this app.

Will I need to create another partition? The last time I did I 'expletives deleted' it up. ;-) This was using a Win 11 machine.
