Sweet, welcome! :) I know the feeling. I just finished reinstalling Nobara after being dumb and goofing up patching. Then I tried to fix it and made the system totally unusable and I gave up.
A while ago I jacked my grub config and decided to try to fix it manually. I managed to stumble through it and learned some stuff, though I am still fuzzy on some details.
I mostly want to just use the computer without a lot of headache and both Mint and Nobara have been great for coding (various), electronics design, 3d modeling and printing, graphics, photo editing, and such.
