It isnt that hard, moved from wondows 10 to mint, and a few months later to arch, and it took me less than 2 hours to install arch, and thats with slow internet.

And i learned a lot whole doing it, like Dekstop environments, disk partitoning(root, swap, and boot), filesystems, and a lot more.

I wouldnt recommend it to everyone, but it is great if you want to learn more about computers.
