For disabeling startup manufacturer logo and showing boot message edit fie:

sudo vim /etc/default/grub

When the files opens change:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash". Keep other parameters if any. In my case, it will be GRUB_CMDLINE_LINUX_DEFAULT="".

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""

Than update grub:

sudo update-grub

Reboot system.
