CentOS - Feb 2010 - Grub boot loader?

Dear All
On my CentOS server , the '/boot/grub/menu.lst' has the right
configuration
but when I reboot my CentOS server I cannot enter to grub edit menu to edit
my boot kernel by pressing the 'e' key . Can you please confirm if I can
activate it through issuing the followings :
#grub-install /dev/hdax
Is it a safe procedure to try with? Please confirm.
Thank you

Are you starting with a <space> to interrupt the boot?

Have you tried editing it using a normal editor (vi or emacs) as root
while the system is up?

What exactly are you trying to do?
