Now better to use minimalist install on my pc only what I use everyday.

when error do nuke the OS.

@blinkwarp make a separate partition for learning purposes and one for productivity.
My old broken laptop has 4 os installed on it's hard drive.
1. Windows
say what you want but this windows pc was unbloated enough to the core to the point it doesnt sends too much request to microsoft server.
Why use windows? Well i still occassionally play steam games and having bumblebee driver was a mess in linux so ? Yeah thats what i thought.
Sorry no guide it's been 2 years since it broke and i forgot how to do that but i can tell you that it involves some host hased blocking and program debloating like cortana microsoft store etc.
2. Debian lts.
I do kernel compiling for my phones here. It's really stable distro. Too stable i might say. I rarely see warning on dmesg.
From my experience I prefer getting my ass blasted off rather than trying to get bumblebee drivers working on debian without touching prioprietary stuff and a whole lot of debugging.
3. Manjaro
It's a neat os if you wan't to learn more about linux (i recommend gentoo if you're a masochist).
To summarize my thoughts on manjaro.
It's a distro For someone who enjoys pacman and arch linux but can't install regular arch linux (lol).
Again bumblebee was a mess on this distro too.
It was fun reading the kernel dmesg.
My experience running this dostro was.
Found error > try to fix it > "fixed" it by myself > program no working || os no boot *suprize pikachu face*
4. I forgot what it was.
It's either opensuse (blazingly fast package manager) or solus os.
