Document Summary
Grub2, the updated version of the grand unified boot loader (grub) utility, is any version of grub 1. 98 or later. The following commands can be used to view the version of grub that has been installed. The actual command used will vary between distributions: grub-install -v grub2-install -v grub2-install --version. Earlier versions of grub are sometimes called grub legacy. Be aware of the following details about grub2: /boot/grub/grub. cfg or /boot/grub2/grub. cfg are the configuration files for grub2 (depending upon the distribution). Depending on the distribution, the update-grub or grub2-mkconfig command generates the /boot/grub2/grub. cfg file. Specifically, these commands use the /etc/default/grub file and the scripts in the /etc/grub. d/ directory to generate the /boot/grub2/grub. cfg configuration file. The /etc/grub. d/ directory holds script files that are read when the update-grub or the grub2-mkconfig command is used. The grub. cfg file should not be edited directly. Instead, the appropriate configuration file below should be edited when a change needs to be made.
