I have been ‘playing’ with grub-customizer … and now after unistall this tool i have realized that i have a mess at the Grub list, all Manjaro kernels and all of the other Debian systems too are displayed at the grub-list. I have been trying to see if there is any information at some place that can help me to find a way of how to eliminate all this entries from the Grub (not from the systems) but …
How to restore this backup
* make sure you have root permissions (`gksu nautilus` or `sudo -s` on command line) otherwise you won't be able to copy the files
* to fix an unbootable configuration, just copy:
* '/etc/grub.d/backup/boot_grub' to '/boot/grub'
* to reset the whole configuration (if it cannot be fixed by using grub customizer), also copy these files:
* '/etc/grub.d/backup/etc_grub_d' to '/etc/grub.d'
* '/etc/grub.d/backup/default_grub' to '/etc/default/grub'
No problem, while you was writing … i did it as i mention it before, reinstalled the grub-cust made all the changes i considered … removed the aplication, grub update, means grub-mkconfig -o /boot/grub/grub.cfg reboot, and evething is back to normal.
My strong recommendation now: never again to play with grub-customizer
