Customize Debian Linux grub2

I wanted to remove the splash image while booting Debian 7 Wheezy and watch the code execute, while also use the full screen resolution.

sudo gedit /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_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD …)

# Uncomment to disable graphical terminal (grub-pc only)

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo’

# Uncomment if you don’t want GRUB to pass “root=UUID=xxx” parameter to Linux

# Uncomment to disable generation of recovery mode menu entries

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE=”480 440 1″

sudo gedit /etc/grub.d/00_header

if loadfont `make_system_path_relative_to_its_root "${GRUB_FONT_PATH}"` ; then
set gfxmode=${GRUB_GFXMODE}
set gfxpayload=keep
insmod gfxterm

sudo update-grub
