I had rEFInd and GRUB installed entirely by accident, and a botched update for Arch hosed my entire EFI setup making it impossible to boot Linux or Windows w/o a LiveCD. Thankfully it self repaired once I nuked rEFInd. I ended up going back to Ubuntu, but I hate snaps. I still would recommend Arch for most Linux users who want the power windows.
Linux
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.

Renaming a mount point while mounted was a fun experience in losing data back in the big box Redhat 5.0 days.
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.
rm -rf /var
I don't know what I was thinking on to type it 😅
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 one day it was outdated and geberating the image failed, I noticed that by the fact that the system refused to boot my OS.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!
This thread should be renamed to 101 reasons why business give Windows or Macs to their employees.
It's not like you can't shoot yourself in the foot while using windows (not sure about macs, tho, but likely just as well). I remember breaking windows countless times while figuring out what service crap can be disabled, removing edge or defender, yada yada.
On the contrary, in my experience, if you're not actively messing with linux, it's overall more stable than windows. Like I had to install windows on an actual machine a short while ago, and it was a clusterheck. Drivers failed to auto install (touchpad/trackpoint drivers, for Chaos's sake), random bsod after an hour or so of normal use, etc. As for linux breaking on itself, I remember like 3 times that happened with me in my ~5 yrs of daily driving different distros, and 2 of those were fixable by switching to a tty (the 3rd didn't boot, as far as I remember, due to some incompatibility between bedrock and arch).
A system update broke a dependency for libre Sprite, which hasn't had an update in like two years. You can say they should but let's be real, my apps shouldn't break with an update. One of my laptop needs was portable graphics creation. This broke one of my major use cases. Yay.
Some Windows updates completely break the whole system. It's not unique to Linux based systems.
