Some laptops don’t really let you boot from external install media so easily nowadays.
I helped a buddy get Linux Mint on their “old” laptop to try it out. But it turned out you needed some manufacturer provided code to unlock booting from anything but the main harddrive within the bios.
We contacted support but never heard back. We did find a work around when they decided to swap the existing HDD for an SSD, they used a USB to sata cable to install Mint on the SSD from their desktop then installed the SSD into their laptop in place of the original drive so it booted straight into that.
You’d be surprised how many people nowadays just leave random shows or movies on in the background while they’re on their phones.
Even my Dad does it, I ask what he’s watching on Netflix, etc and half the time he has to check even tho he was the one who clicked on it in the first place…
