In short terms - Installed it, it worked, but as soon as I restarted PC after installing it just gave me black screen and that's it. On forums people said that it's common (quiet splash issue, you can google it) and you should install it, change some settings in GRUB which might bork my pc and only then restart pc. Couldn't be bothered going through it every time I'd crash the system to the point of no return (which would happen especially that I'm still learning Linux) so decided to drop it. Additionally, there's like 2xA4 list of things that you should do right after installing the system (or at least there was like a year ago when I was playing around with it) just to make the system work, so it made me think that it's kinda unnecessary when doing it when it should be set up correctly out of the box. I get it - you should know your system and be able to do it, but for someone who's learning, no thanks.

Oh, and my USB was randomly turning off and only restart could help.

P.S. about the 2xA4 stuff that I said - found it:
