I accidently rebooted during pacman update and now my system dosen't show option to boot into endeavour os. Systemd just shows option to boot into firmware interface please help! - Lemmy

I’ve lost everything and I don’t know how to get it back. How can I repair my system all I have is a usb with slax linux. I am freaking out because I had a lot of projects on their that I hadn’t pushed to github as well as my configs and rice. Is there any way to repair my system? Can I get a shell from systemd?
