Once you get it all setup and proud of your work, make a fucking backup image, because a single update that changes an obscure library in some forgettable package that was part of your install will break everything and you will be pulling your hair out kludging a CLI script to unfuck some other binary that was unimportant, but now has affected another thing that was crucial for a graphics card or network adapter to function.

Steam runs pretty smooth on Linux. Am currently using OpenSuse. Steam runs smooth. Games run smooth with one or two exceptions. For those exceptions I have a dual boot Windows 10 that doesn't need Windows Update for anything I ask it to do.

Do you have a separate computer that you can use to do a “test run” of using Linux? If not, I would at least play around with Linux in a virtual machine before committing to the bit (and I say this as someone who has been using Linux laptop / Windows desktop for 6-7 ish years now)

If you have a spare drive on your PC I'd recommend trialling Linux on that. With that setup, you will have it dual booted with your existing Windows installation. It should help with the transition since you can just boot into Windows if you still need it for anything. That will give you time to get accustomed to Linux while still having that Windows safety net for a while.

Also if you later find that Linux isn't for you then it's easy to undo that, since all you will need to do is boot into your Windows drive instead.

I went with that strategy when I made the jump 4 years ago, and later dropped Windows entirely when I built my new PC a few months later since I realised I didn't need it at all.

Just get another disk or partition and get it running on that. If it goes fucky, boot into Win and game, try again later.

I was dreading trying Linux as well and it was nowhere near as bad as I anticipated. Did full transition (I got new SSD for dual booting to try the waters) to it much faster than I ever anticipated.

I mostly just use the PC for gaming though so mileage may vary.

Bazzite was a 15 minute experience for me, from first boot to playing X4 foundations and sea of thieves.

Take the leap.

If you're switching over with gaming in mind, then using Bazzite or Nobara will make it so you have no head banging. Bazzite has everything you need for gaming all ready to go, and since it's an immutable distro, it'll be difficult for a newbie to fuck up on accident.

I have to say, in general this doesn't happen too often. But if you are afraid of this scenario specifically, my advise is either use a separate partition for the home folder (this is where all user installed things go, as well downloads, documents and pictures by default) and make a backup in some other drive with something like timeshift, or use something a bit more advanced namely immutable distro. I will give a bit of advise here: immutable distros can be extremely unintuitive, so if you want to try and understand it, go for a VM and take a weekend playing around. For gaming, bazzite comes to mind for this specific case.

Honestly, just install Kubuntu 24.04. Install it and forget it. It's super stable and has great support. Whatever people argue about the Snap packaging system, that will be almost invisible to you as the end user.

Make a dual boot system. You can continue to use win10 while getting comfortable with linux. If something breaks just reboot.

Windows 10 isn't going to suddenly stop working the instant it's "EOL". If anything, I'm looking forward to no more random reboots at 3am following a mandatory update that didn't do anything useful.
