Boot <--> Grub

[James Dee]

Hello everybody,

I have three systems on my computer.
1st installed --> WinXP
2nd installed --> Intrepid Ibex
3rd installed --> Hardy Heron

At the moment while booting the grub from 3rd system is on.
How to setup that grub from 2nd system is on during booting?

I'm just curious and like to learn something new.

It depends if You are using grub or grub2 ... I'll assume You are using grub (the "old" one) ... In that case in file /boot/grub/menu.lst change the line "default 0" to "default x" where x+1 is the order of OS in the grub list (the order You see at boot i.e. the order in which they are listed in aforementioned file) You want to use.
Be careful since if You mess up that file You could be left out of Your computer for a while before You master using LiveCd to regain control ...
To edit that file You could use

sudo nano /boot/grub/menu.lst

I'm a bit rusty on using grub so take this with a grain of salt ...

How to remove 3rd system properly?
At the moment menu.lst from 3rd system is called during booting. If I want to remove 3rd system (menu.lst will not exist anymore) I need to change that menu.lst from 2nd system is called. How to do that?

I've never done something like that, so I'll pass on answer even though I have several solid ideas ... but I do not like to speak about something I've only read about. ... Sorry.

Super Grub Disk should correct any grub difficulties you have after deleting your 3rd system(http://www.supergrubdisk.org/)

If you are going to change/alter/edit the grub file "menu.lst" then you should make a back-up copy first

sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.old

Then you can open an editing session with

gksudo gedit /boot/grub/menu.lst

Boot Ubuntu.

Fire up grub :

sudo grub

At the grub prompt :

grub> root (hd0,x)
setup (hd0)

You need to know which partition is the second OS.
