By default Debain no longer displays the any output while the system is booting, however it can be quite useful to see what is going on particularly when trying to debug a system that isn’t behaving.
Fortunately it is quite easy to get these messages back.
You need to edit ‘/etc/default/grub’ at root and remove the “quiet” option from the GRUB command line.
# nano /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` #GRUB_CMDLINE_LINUX_DEFAULT="quiet" GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_CMDLINE_LINUX=""
Note – It is just a personal preference but when making this sort of change I prefer to comment out the original entry and create a new one.
The you need to update grub.

You should see the boot messages on the console next time the system starts up.
