I've been trying to get an HP elitedesk 705 G1 mt to boot from dvd. So far no luck. I've managed to get DVD listed as the first boot entry for both UEFI and legacy. The machine seems to try and fail. The error messages go by rather fast. I think I've seem things like "invalid header" and "no such file", but am not as sure as I'd like to be. Most recently I tried and failed with Fedora-Workstation-Live-x86_64-39.1.5.iso
Any idea what I should try next?
My late girlfriend used it. I remember her password, which is why she is not on the sudo list. I do not remember either the root password or my own.
