Grub - How can a new menu.lst file be automatically generated when running 18.04?
0
When on Ubuntu 16.04, if any unintentional edits were made to my /boot/grub/menu.lst file I was able to delete the file, and then run "update-grub" and I was prompted to generate a new file. After upgrading to 18.04, however, it appears that grub gets uninstalled and this command is unavailable (unless choosing to reinstall grub).
Taking this into account, what is now the suggested way of carrying out the above?

Grub2 doesn't use a/boot/grub/menu.listfile but uses the configuration file/boot/grub/grub.cfg. This is the case for 16.04 and 18.04. I also don't see why upgrading from 16.04 to 18.04 should uninstall grub in any way, that's not the case. Did you have an older version of Grub installed in 16.04 before upgrading? That would explain the confusion.

@mook765 actually, there is a/boot/grub/menu.lstfile even with grub2.

@terdon I don't have/boot/grub/menu.listin any of my installations, yours might be a left-over from upgrading. gnu.org/software/grub/manual/grub/html_node/…

@mook765 yes, you must be right. I checked on another machine and that one didn't have it. I was actually about to write the same basic comment you did but checked just in case and was surprised to find the file! I know I haven't used themenu.lstfile in several years, not since the switch to grub2 anyway.
