I know this is an amateur question, but I want to make sure that I do it correctly the first time. I want to add a boot parameter, so what file do I edit/create to do so?
My computer doesn't have a /etc/default/grub file. I can't tell you why. I didn't intentionally delete it. I have a bunch of configuration files in /etc/grub.d , but I don't want to touch any of them because I don't know what put them there or if/when they'll be overwritten. Is there a way to generate a default /etc/default/grub file that I can edit? I'd think after 30 years there would be a command to do that, but over an hour on the Internet yielded nothing. With thanks,
