Thanks for your message . When I reboot my CentOS server I see the the menu with a timer but I cannot enter to edit my boot kernel by pressing 'e' key .
Perhaps I wasn't clear the first time. To interrupt the timer, you press the <space> bar. You can't edit anything until after that point.
Then the timer will expire and the boot process will begin . I want to be able to edit my kernel through grub edit so I asked if I can try for 'grub-install /dev/hdax' w/o any harm on my CentOS server . Do you mean I can edit my '/boot/grub/menu.lst' by vi the same as I want to do inside my grub edit ? Are they the same procedures ? Please confirm.
Yes, you can just edit the menu.lst with any text editor. /boot/grub/menu.lst is a symlink to /boot/grub/grub.conf, same as /etc/grub.conf. You have to be root to edit it (them).
grub-install won't do what you want.
