Alright, just going to make the post even though I'll probably ask dipshit questions, but I'm starting from zero here. I'm going to make the jump to Linux for obvious reasons and I've been wanting to for a while anyways. I have a Steam Deck and I've fucked around in Desktop mode a bit, so that's my whole experience with Linux itself, not even m+kb but enough to have some basic console/flatpak/etc. experience.

For most of my PC use it's about
>50% web browsing/watching videos, media storage and playback
>35% games, mostly older ones, not a lot of AAA
>15% audio recording/cutting, minor game modding/file fuckery, some video editing, etc.

So Bazzite seems to fit that since I'm mostly worried about drivers/hardware compat and games just werking, least friction for my usecase. I'm going to try Rufus to boot it from a USB first and fuck around a bit before fully installing it on a drive (Have a new 4TB SSD to replace my Windows boot). Is there any real requirement for that flash drive or something I should look out for on that? Don't intend it to be a truly long-term solution but figured I'd ask.

I'll keep my old Win10 on my current SSD and swap it to another slot. Be the first time I actually attempt dual booting, have a visual bios system so should be easy to swap them if I have to. Is it that easy or anything to watch for/smooth that? I'm also more concerned on file format for the drive. I know trying to set up/transfer stuff to my Deck I ran into issues with the NTFS windows just not recognizing it; should I just be able to read my old NTFS drives straight in Linux and go from there?

Finally, there a good basic "starting point" to read up on Linux basics? Stuff like commands, distro differences, etc. Obviously the OP, and I don't have an issue reading documentation, but didn't know where to start. For instance, on the babby guide, no clue what dpkg, rpm, pacman differences are. I assume something about package installation but don't know choosable differences.
