Installed neon on an external drive. Liked it so much I cloned it to my internal drive. Spent 4 hours trying to diagnose why I was being dropped to a grub shell every time I tried to boot. Apparently the bootloader ID was fine being "neon" on the external drive but had to be "Ubuntu" on the internal drive or grub wouldn't find it. Fucking infuriating, but I like plasma 6!
