I'm trying to install Oracle Linux 8.1 on VirtualBox 6.1 virual machine.
Steps I took:
Step 1 - Download ISOs from Oracle SDN with DLM
So here I have the first question: what are those ISOs? Why it isn't a single one?

Step 2 - Create VM and insert ISO
With trial and error I found which one to use to boot into setup - it's V984215-01.iso

Step 3 - Trying to actually install Oracle Linux 8.1 and getting the error
So here's where I'm stuck. For some reason "Loical Media" installation source is missing.


Questions:
- What I did wrong?
- How to fix?
