redhat 5.4 installation problem
 

while installing redhat 5.4, in grub boot loader screen, can we replace that picture by any other.....???

plenty of docs out there - http://ubuntuforums.org/showthread.php?t=30341

a please / thank you would be a good idea next time. :)

Google gave me some of the links, changing spash images. Did you try that?
And please give an appropriate title to your thread which should be meaningful, then it would be better. The title you mentioned is "redhat 5.4 installation problem". And the problem you described is not an OS installation problem.
