Wanted a cool bootscreen on my Nixos machine - commented out the bootloader to troubleshoot, why my meme-boot-picture wouldn't show - after rebooting, it loaded straight into the BIOS and finally realized what I had done... Was able to fix it thankfully

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Before I understood how to properly build and test mesa (graphics driver), I compiled it and then procedeed to manually symlink the files in the lib and lib32 directories. When I pressed enter on that ln command, the UI immediately crashed and X would no longer start after rebooting the computer. Reinstalling mesa from a virtual terminal wouldn't fix it so I just reinstalled the system. Good times :)
I somehow locked myself out of sudo when trying to give my user permission to read serial devices.
Had to reinstall.
Can't say I have any interesting stories. Most of mine are just the head-scratching "I don't know why that didn't work; guess I need to reinstall" kind of story. Like enabling encrypted LVM on install and suddenly nothing is visible to UEFI. Or trying to switch desktop environments using tasksel and now I have a blank screen on next reboot. That lame kind of stuff.
My coworker though... he was mindlessly copy/pasting commands and did the classic rm -rf $UNSETVARIABLE while in / and nuked months of migrated data on his newly built system. He hadn't even set up backups yet. Management was upset but lenient.
Renaming a mount point while mounted was a fun experience in losing data back in the big box Redhat 5.0 days.
Relied on an AUR package for building and signing my unified kernel image... one day it was outdated and geberating the image failed, I noticed that by the fact that the system refused to boot my OS. Fixing it was done in a few minutes but boy, that was a shock :D
Guess who also checks the exact output of the kernel rebuild now before rebooting!
The first time I installed Fedora after like a decade I updated to new minor version -> sudo reboot because I was already in the terminal -> reinstalled because it wouldn't boot anymore
