How to update GRUB ?

if multiple distros are installed, overwriting grub.cfg will destroy the ability to boot a different distro

So, update (append) entries with any of the following method

  • to append the new entry at the end of grub menu
grub-mkconfig >> /fat/grub/grub.cfg
  • to add the new entry on top of the grub menu
grub-mkconfig > grub_menu
cat /fat/grub/grub.cfg >> grub_menu 
mv grub_menu /fat/grub/grub.cfg

unneeded entries can be carefully removed from /fat/grub/grub.cfg

  • a grub entry
    • begins with ### BEGIN
    • in between : menuentry "name_of_installation"
    • ends with ### END
