edit
/etc/default/grub, change the line GRUB_CMDLINE_LINUX_DEFAULT="quiet" to GRUB_CMDLINE_LINUX_DEFAULT="splash"

splash: this option is used to start an eye-candy "loading" screen while all the core parts of the system are loaded in the background.
-
run
update-grub2 or update-grub to reload the config
