Custom GRUB splash image in Fedora/Redhat/Centos

• Log or Switch in to the root account

• Get an image file to use for the new splash image (can be some wallpaper in jpg, png format)
  

• Check whether ImageMagick rpm is installed

# rpm -q ImageMagick

• If it's not installed you have to install it first

# yum -y install ImageMagick

• Then, Assuming the image is in the root's home folder & the image name is "myboot.jpg"

# cd
# convert myboot.jpg -resize 640x480! -colors 14 -depth 8 myboot.xpm
# ls

• Now you will be able to see a file call "myboot.xpm"

• Then you have to gzip it.

# gzip myboot.xpm
# ls

• Now you will be able to see a file call "myboot.xpm.gz"

• Then you have to copy it to "/boot/grub" folder

# cp myboot.xpm.gz /boot/grub

• Then you have to edit "grub.conf" file with your favorite text editor, I'll use "nano" text editor

# nano /etc/grub.conf

Edit the following line

splashimage=(hd0,0)/grub/splash.xpm.gz

to

splashimage=(hd0,0)/grub/myboot.xpm.gz

NOTE- DON'T EDIT ANYOTHER PARAMETER OF THE LINE, ONLY CHANGE THE IMAGE FILE NAME.

save & exit

• Then reboot your system

# reboot

• Then you'll be able to see the new GRUB spalsh image during the startup.
