Hiya! I have a known good Ubuntu 22.04 USB that has worked on other devices, but when I try to install it on this PC I get a blank screen with “stdin: Invalid argument” repeated 30 times or so, and at the bottom it says “Unable to find medium contained a live file system” and then attempts to boot from URL. (For some reason lemmy won’t let me upload a picture!)

I’ve tried multiple different USB ports, I’ve looked at the BIOS and can’t find any secure boot or legacy stuff that needs to be disabled. Not sure how to progress!

Help would be greatly appreciated <3
