Hi tcl-newbie

If you're using grub a bootloader the file is called menu.lst.
you can also search it
sudo find / -name extlinux.conf resp.
sudo find / -name menu.lst ...
Depending on your setup, a search like that can take a long time. For example, if you have any network drives mounted,
it will also search through all of them. If you have a general idea of where the item you are searching for should be,
specifying a partial path will avoid needlessly searching the entire directory tree. In this instance, your search is for one
of the files used by the boot loader. Even though you don't know where it's located, you know it must be on a persistent
storage device, so you could narrow your search like this:
sudo find /mnt/sda1 -name extlinux.conf
