Does the bios have an option to EFI boot from a USB? Sometimes there is a tiny file manager in the boot options that will allow you to boot from an EFI file off a USB key and not just by selecting a different boot option, the issue here seems to be that the firmware is trying to boot from a file that doesn’t exist. The odd part is that it won’t work from your USB because it seem to be trying to chain boot efi files that don’t exist.
Are you sure your live media is good? Does it boot on another system?
Glad I could help, please leave an upvote on your way out :))
