I'm trying to update my grub boot order back to booting the first option instead of the second, so I run sudo nano /etc/default/grub, but it brings up this, which is not the file I want to edit.
Sorry, I think I forgot to update my original post to mention this, but I think I somehow overwrote this file with the contents of grub.cfg so that file is no help to me.
sudo mv /etc/default/grub /root/old_etcdefaultgrub to get it out of the way, then sudo dnf reinstall /etc/default/grub to reinstall the package that provides it, giving you a fresh unmodified copy. Should work for practically any config file on Fedora.
Did you even try? A bunch of people, including myself, gave you plenty of suggestions.
If you're expecting to have your hand held and the solutions spoon-fed, consider Windows or macOS. If you want to use Linux, you have to help yourself, or at least help us help you.
I am sorry, I have been very busy and was planning on getting back to this when I have the time. I have done a lot of searching over the past months, and the comments on this post have mostly been very helpful and seem like they will work, so that's great actually. I am sorry if my post comes off as lazy or something, because that is not my intent.
