Super noob at this and am definitely stuck so I uninstalled and starting from step 0. One of the biggest issues I was having is after downloading bitcoin core, without even running the program, I am looking at the folders and I don't see a folder for the wallet. On my last attempt, The folder didn't appear until after I ran bitcoin core and clicked create wallet and named it "test". After following the steps on this post and watching numerous videos what I'm getting at is I need to replace the "test" wallet.dat file with the backed up wallet I am trying to access. After I do this however, when I click file>open wallet>, I only see "test" and not the other wallet. In my previous attempt I had first synched, closed bitcoin core, replaced existing wallet.dat with the wallet I am trying to access, and then ran bitcoin core again. The message I received was something along the lines of "Wallet loading failed: Prune: last wallet synchronization goes beyond pruned data. You need to -reindex. (download the whole blockchain again in case of pruned node)" Clicked ok and then ran bitcoin core again. This time I don't recall the message I received but it was a different error and I assumed it was because I did not have enough storage to download the whole blockchain again. Now I will be beginning from scratch on a different device.
Would someone please be able to help me out with a step by step that a third grader could follow? Thank you in advance!!!!!
