A few years back, I was installing Arch on an external hard disk. I was basically done, so I powered off the system, but I forgot to unmount the hard disk.
Then I tried to boot to the OS on my computer, which was also Arch, and it got stuck at the BIOS splash screen. No luck rebooting.
I remember panicking (because that was my only machine) and asking my computer teacher what to do and he also had no idea.
I ended up manually unplugging and replugging the hard disk inside the case and it worked. To this day I still don't know what went wrong.
This is an assumption I made from observing users on Lemmy. I want to further understand their reasoning, and therefore put the assumption in the question.
Because it's already the cliff, the mountain, the river, the ocean, the cosmos, whether you like it or not.
