just built myself a pc. installed linux mint via usb. after clicking reboot this error shows up. manually restarting(turning it on and off) linux starts normally. google doesn’t help at all. i don’t even know where to start maybe someone here has an idea?
Sure. If it’s only the installation USB stick you probably don’t need to pay attention to it if it installs fine. Next time I’d try and check if the image got written correctly to the stick.
