unable to configure /boot/grub/menu.lst
 

I tried making some changes to /boot/grub/menu.lst file by logging in thru su but it throws following error:





[root@localhost avi]# /boot/grub/menu/lst | gedit

(gedit:4874): GnomeUI-WARNING **:

While connecting to session manager:
Authentication Rejected, reason : None of the

authentication protocols specified are supported and host-based authentication

failed.
bash: /boot/grub/menu/lst: No such file or directory

help me with the reason and solution.

Thanks in advance!

Should you not be typing /boot/grub/menu.lst

/menu/lst refers to file lst in directory /menu

yeah thats correct...ll try out...thanks!

What distribution and desktop are you using?

Always give as much information when asking for help so we're more likely to be able to help with the problem.

Looking back, I see you're using Gnome which I'm not familiar with. Maybe someone with Gnome knowledge can help you.

sudo gedit /boot/grub/menu.lst

yeah m using GNOME.could u please explain this part in the error mesg.:

"While connecting to session manager:
Authentication Rejected, reason : None of the

authentication protocols specified are supported and host-based authentication

failed"

You are trying to open a gui app while being root .

With distro are you using ?
With GRUB are you using GRUB 1 ore GRUB 2 ?
You see GRUB 2 do not have a menu.lst but a GRUB.cfg
Editing GRUB.cfg is not recommended .

is that forbidden?
how can i edit /boot/grub/menu.lst on CentOS?(i gt the abv error while trying the same task)

Try this:

In Fedora, I get a screenful of error messages if I try the equivalent
su
gedit /boot/grub/grub.conf
but Gedit does eventually start. The same thing happens if I try to launch Nautilus. The Ubuntu version of the Gnome session manager is obviously fussier than the Fedora one.

The obvious solution for you is not to use Gedit: try nano instead.

I am using win7,ubuntu and CentOS in multiboot.I have restored the ubuntu's GRUB-2 but now its not listing CentOS in the boot options.Could you please suggest the tweaks to get the same?

Try in terminal the command sudo su update-grub
If it does not work post again
Restart you're computer to see if it works

Is it grub 1 or grub2?
 

I had a similar problem. In my situation grub2 was running from Mint and wouldn't recognize that Fedora was on my hard drive. The Fedroa forum worked on it for about a week.

The answer came when someone realized there was a way to get grub to do the dirty work from the comand line. And yes, you can't/don't want to edit grub2!
The short, sweet and brutal solution:

"there is something called Startup Manager for Ubuntu. Maybe a graphical representation of what you want to do? Point and click menu editing? Just a thought while I was reading through my GRUB2 notes."

And that did the trick! After about a week of agonizing by what seemed like all of Fedora's team. When I ran it, Fedora was listed. It's at the last page of a post that's longer than most books in the bible!

thanks a lot!
lemme c if it works fr me!
