Funny anecdote, I installed Ubuntu on my own laptop to improve my minecraft FPS when I was 9 (~9 years ago).
I googled something like "how to get more fps in minecraft" and the first result was a minecraft forum post to which the only response was "install Ubuntu". At the time, Ubuntu had a .exe installer, so I thought it was just like any other program and installed it to my C: drive along with everything else. I think I did have the concept of other OS since I'd used both Windows and MacOS previously, so I figured it out after the reboot. It did increase my minecraft FPS from ~15 to ~30 on average, so I didn't have any complaints.
I stuck with that laptop until high school, when I got a new laptop and started dual-booting Windows for gaming and Linux for everything else, which is where I'm at now.
Indeed funny! What happened after you installed the .exe Ubuntu? You clicked the icon and then ..?
I'm just past the 'stage' you're in now, I recently deleted my partition running Windows (kept it for GTA5). Only Ubuntu now.
I don't remember much about the installation process. I think I just got to choose between automatic or manual partitioning, which is when I presumably went with automatic and chose the C: drive.
Are you able to play GTAV on linux? Or just given up on the ability to play it? That and a few racing sims are the only things keeping me on windows these days.
Not the person you're replying to (and I don't play GTAV), but you can look here to see if it works in Steam via Proton: https://www.protondb.com/app/271590
It's rated Gold, and appears to work out of the box for some people, others have had to add an option to the command line that Steams uses to run it, and some people have seen some problems running it.
If you do end up going this route and try it, please file a report on protondb letting others know how it went.
You may also want to check out PlayOnLinux which eases the creation of sandboxed installations for different Windows software (not just games), in which each one could use its own Wine version, libraries, modules etc.
