Uninstalling rEFInd and locating partitions

[Elphor]

So i had a dualboot with widnwos set up however, I recently got an external SSD so I'm planning on installing it there, and I can't seem to be able to remove it. I went ahead and wiped the partion that had windows installed and fused back together with the steamOS one.

I am basically trying to remove rEFInd and anyone knows how can i differentiate which partition is for what? i have one for windows recoverey, steamOS recovery and rEFInd but I can't tell the difference between them and I'd like to remove the windows one for starters and then then uninstall rEFInd.
