Today I read Remove Boot Text On The Raspberry Pi For Noobs:

vim /boot/cmdline.txt

You will see a single line with all the boot options. Scroll along and change the following making sure not to add any linebreaks:

• Replace console=tty1 to console=tty3 to redirect boot messages to the third console.
• Add loglevel=3 to disable non-critical kernel log messages.
• Add logo.nologo to the end of the line to remove the Raspberry PI logos from displaying

vim /boot/config.txt

• add disable_splash=1 at the end of the file.
