I hope you find it a suitable replacement, I haven’t used Windows in years thanks to Linux.
My advice, the good documentation on parts of Linux is quite literal it’s best not to skim over sections. Sometimes the authors choice of words will infer answers to questions you might have.
A bit of competency in the shell/command line will go a long way, being able to view hardware (lsblk, lspci) mount drives, traverse the filesystem (ls, cp, mv, chmod etc) and a few of the basic commands for example
This should give you the ability to:
-
Back up all your important data from a live environment in the event that your distro is completely borked before reformatting
-
Gives you solid foundations to learn more in-depth parts of Linux if needed, access to internal documentation (man pages etc) from the shell itself is useful too.
Don’t be afraid to dive in, it’s hard to break things learning the basics if you’re not root.
Managed to wreck my NVMe drive with an unsafe shutdown on linux the other week, gave it a few hours for the self check, booted back into the distro and has been running fine ever since.
Pretty sure windows would’ve just set the computer on fire at this point.
