GRUB2 issue

Asked by Athani

I updated from Jaunty to Karmic Alpha 3. I installed GRUB2 from Synaptic. I have confirmed that GRUB2 works on my PC as I can see it as an option in my original GRUB and can boot to OSes using it. Now I want to get rid of the original GRUB. Following the steps on https://wiki.ubuntu.com/Grub2 did not work. What shall I do?

You edit the menu.lst in /boot/grub carefully and remove the entry for the old GRUB.

Hope that helps

I'm giving my menu.lst file contents below. Kindly tell me what to do. I also want to remove the old GRUB loader. And to change the order in which the OSes appear. Thanks.

# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 10

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu

# Pretty colours

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing

I mean that I also want to change the default OS to Windows XP as my girlfriend is not comfortable using either the GRUB or Ubuntu.

I'd tried a command. Please see the command and the result below.

chandan@chandan-desktop:~$ sudo update-from grub-legacy

     One of the reasons I love to check on this daily is that I learn so many new things....I wasn't aware there WAS a grub2. Having looked at this and checked for others with an internet search, I found a successful user of it at:
http://gastly.iblogger.org/how-to-install-grub2-on-ubuntu-jaunty/ who gives instruction. It looks like the only thing different is that you didn't hyphenate all the words and used 'update' instead of 'upgrade' - it maybe should have been "sudo upgrade-from-grub-legacy" instead of "sudo update-from grub-legacy". According to the 'gastly-iblogger', that worked fine.
     I saw others during the search who said the splash screen was ugly and they wanted to change it. You might want to try searching for grub2 on the internet if you agree.

Hi,

I did type 'sudo upgrade-from-grub-legacy' in the terminal. But I get the
following in the terminal window and I can't do anything after that except
to close the terminal window. The "OK" at the bottom of the window is not
click-able.

 │ In order to replace the Legacy version of GRUB in your system, it is

 │

 │ It's recommended that you accept chainloading GRUB 2 from menu.lst, and

 │ verify that your new GRUB 2 setup is functional for you, before you

 │ install it directly to your MBR (Master Boot Record).

 │

 │ In either case, whenever you want GRUB 2 to be loaded directly from MBR,

    Seems sad it isn't working as well as it should.
    I wonder if the <Ok> is 'selectable' by using the TAB key, in which case the Enter key would 'click' it. That's more of a Bash (shell) style, which doesn't use the mouse...

I performed a clean install of Karmic final release.

Thanks to everybody who helped.
