[TL;DR: I’m looking for resources on Linux so I can catch up and become reacquainted with it. Are there any all-encompassing media about Linux itself, and stuff like backing up, snapshots, file systems, dual-booting, customization, etc. I can use as a reference/ learning material?]

Some background: I used Linux Mint a small bit about 10 or so years ago to save some old hard drives. (Windows 7 era)

I braved Windows 10 but played in Linux VMs as I started to self-teach programming. Things changed when I got my hands on a Steam Deck a few months ago and I fell back in love with Linux. I had no idea how much progress got made. It runs so well and I like the ecosystem.

Last month, I built a new computer. Right before the RAM and SSD shortage (I’m talking mere days). Because of some programs I use, I put Windows 11 LTSC on it, but I want to downgrade back to 10 because it’s just so awful. And I’m sick of M$ antics and performance, so I want to dual boot.

All that being said, if there are resources for learning Linux from the ground up or anyone I can approach with questions, I would appreciate some direction there. Many thanks!
