linux dd error! Error! grub.cfg.#
Error message#
When using the DD script, an error occurs:
Solution#
Enter the /boot/ directory and you can see the following files, including a grub folder. Enter the grub folder and you can see grub.cfg. Obviously, this is grub2.
There is only a grub folder under the boot directory. Since the directory where the grub2 configuration file is usually located is /boot/grub2/, it is possible that there is no grub2 folder.
Create a grub2 folder and use the following command to generate the configuration file:
grub2-mkconfig -o /boot/grub2/grub.cfg I tried this, but it didn't work
mkdir /boot/grub2 && grub-mkconfig -o /boot/grub2/grub.cfg //Alternate command
