My Ubuntu server (which has been working for a few years now) recently asked me in a full-screen prompt while updating something about GRUB. There was a list of partitions with just one element, which is the partition that GRUB os on. I was focused on something else so I just hit enter, but now I am really scared to reboot it. Is there any way to pull this back up or to double-check that everything is ok with the machine?
My cybersecurity course uses Linux… in a VM. We boot into Windows 10, then start Kali in VMware and do everything inside of it. I still don’t know why, I just bring my own laptop with NixOS and add whichever package we are using to my shell.nix for that course.
