You forgot --no-preserve-root

Luckily for OP, Bazzite won't let you do this. Not this easily at least.

Bazzite allows for tinkering just fine, it's just different so you have to be willing to put a little time in to learn how ostree works, for example.

Personally, I recommend quitting Windows cold-turkey and not dual-booting at all. If a game genuinely doesn't work without dual-booting, you don't need it. No game is so important that it's worth compromising your security, privacy, and property rights over.

but dont dual boot on the same drive! get a second SSD or something because windows is a big bully and always wants to screw stuff up

i would suggest looking into alternatives to Ventoy, as the community has been actively discussing the 'blobs' of precompiled code. What this code does is unknown so you are trusting that there is nothing that could be harmful. I personally wouldn't trust it until the below thread provides more clarity.

ventoy is awesome, my tip for OP is to always have a live usb in case of emergencies. you can just install ventoy onto a USB and drag and drop your bazzite ISO but having a live stick you can plug in and boot from at any moment is 100% a life saver. whether you broke something or you just wanna troubleshoot (think windows safe mode but better) you'll be glad you kept that USB lying around :)

I'm using GNOME, so I have ProtonPlus

I've seen Plasma, Xfce, and GNOME. I like the last one the most, so I'm using it on all of my systems.

Love me some Plasma. I'm still running the default styles after over a year as well. It's just nice.

I really should spend some time experimenting with customizations though

Nice, thanks!

Meh, I've found that Heroic works just fine for most offline installers. YMMV of course.

Also worth checking out all of the pre-made "ujust" recipes.

Just type "ujust" in the terminal for a list. Tons of useful shit.

Yeeeah, for a fresh Bazzite install I'd agree that "swap Lutris for Heroic" is solid advice.

In Bazzite flatpak is the way so much that you will open Discover and only see flatpak, so if this was really, really beginner tips I'd suggest not learning what any of that means for as long as possible and just relying on Discover for your apps until you hit a roadbump. This guy seems well informed enough that is not a problem, but hey.

I'm also mildly annoyed that ujust is important enough to still need that terminal splash screen but not enough to be baked into the config tools by default in GUI. So weird.

That's either another thing you should try not to learn about if everything works fine out of the box or something you really should look into if it doesn't, and that's not great.
