Big Linux Trial

[SBP1307]

I changed an old iMac to Linux 22.2. This is my current system on the iMac. I want to try (Not Install) Big Linux. I have created a bootable iso on a USB drive, and when I click on it in boot menu, after connecting to wi-fi, the screen shows several choices. Which should I select?

Welcome to the forums
