CentOS

hi

Howto update Grub on CentOS 6?

I've tried update-grub[code] # sudo update-grub
sudo: update-grub: command not found
# grub --version
grub (GNU GRUB 0.97)[/code]but it doesn't work.

What do you mean by "updating GRUB"? Update-grub is an Ubuntu command to re-generate the GRUB 2 configuration file. CentOS uses GRUB 1 a.k.a. "legacy GRUB", so there's no need for update-grub, grub-mkconfig or any other similar commands. You can edit the configuration file /boot/grub/grub.conf with any text editor.

I need to re-generate the GRUB configuration file to find out automatically boot entries from other linux OS, installed on the same machine.
Anyway, if this doesn't work, I will edit the configuration file /boot/grub/grub.conf with a text editor.

There is no automatic discovery and GRUB update mechanism in CentOS/RHEL.
