Yes, but you have a better alternative, to edit the file

/etc/default/grub
and the files in

/etc/grub.d
instead, and run

sudo update-grub
to rewrite grub.cfg according to the new content in those files.

Thanks sudodus.
I could change from /etc/default/grub and it updated the /boot/grub/grub.cfg to the customized settings.
I am not sure if I will meddle with the /etc/grub.d as it seems suitable for advanced user. which i am not.

I'm glad you worked it out :KS

I think you can manage the files in /etc/grub.d too, reading those Ubuntu help pages about grub, and with a little help from the Ubuntu Forums :-)
