Remove 2.8 and dual boot 3.4 with Ubuntu

[phil66]

All three items returned positive comment as you stated.
I booted ll-3.4 and now was getting to update and use synaptic
But I no longer have a valid password
Looked in help session and found a program for resetting password
This program written by Jerry for ll-3.0
Can i use to reset the password in ll3.4

[gold_finger]

You didn't say, but I'm assuming you ran the chmod command on os-prober script and can now boot into LL3.4.  Correct?


Now you just need to get rid of old entry for LL2.8.  To do that you'll need to open the 40_custom script with a text editor as root/admin and delete the custom menu entry.  I don't know what text editor you have on Ubuntu, but I think it might be gedit.  So, I'll use gedit in commands below.  If that's not the text editor you have on Ubuntu, substitute the correct one in place of gedit in the command.  (If you're not sure, just open the text editor and go to Help->About and it should say what name of editor is.)


To open the file as root in the text editor use this command in a terminal:

Code: [Select]

gksu gedit /etc/grub.d/40_custom

In the opened file, delete everything after the line:  # the 'exec tail' line above.  You should then only have this in the file:

Code: [Select]

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

Save the file, then close the text editor.


Back in the terminal, now update grub one more time.

Code: [Select]

sudo update-grub

Now you should only have Ubuntu and LL3.4 choices for booting in grub menu and Ubuntu will be first (default) choice.

As suspected, the os-prober script has been de-activated in Ubuntu so it doesn't run when doing an update to grub, therefore doesn't add entry for new LL3.4.  You'll need to re-activate it by running this command from a terminal in Ubuntu:

Code: [Select]

sudo chmod 755 /etc/grub.d/30_os-prober

Now run command to update grub:

Code: [Select]

sudo update-grub


Reboot and you should see an entry for LL3.4 and be able to boot into it.


In all likelihood you'll still see an old (non-working) entry for LL2.8 as one of the choices.  I suspect that 40_custom script in Ubuntu's /etc/grub.d folder may have been used for that.  Post back output of this command from a terminal in Ubuntu:

Code: [Select]

cat /etc/grub.d/40_custom

Output confirms LL3.4 installed, os-prober command sees it, but update-grub command does not.  Ubuntu's grub.cfg file still has old LL2.8 entry.


If memory serves me, LL2.8 is a version that did not play well with others if its grub was not the one in control of booting.  (I believe that is no longer the case with newer versions of LL.)  So my best guess is that you must have had to manually do something special in Ubuntu to make an entry that would boot LL2.8 and to de-activate the os-prober script from running when performing an update to grub (eg. for new Ubuntu kernels) so that grub updates would not break ability to boot LL2.8.


Boot into Ubuntu and post back with output from this command please:

That's strange -- don't know why it would be showing LL as 2.8 still.  When you installed LL3.4 did you remember to check the box to format the root partition (/dev/sda3) that you installed to?  If not, do the installation again and format the partition.


Otherwise, ...


Boot into Ubuntu, open a terminal and post back here with output from following commands.  (See this post for instructions on how to post terminal output to forum using code blocks.)

Code: [Select]

sudo os-prober
cat /boot/grub/grub.cfg | grep "menuentry '"(NOTE:  "menuentry '" part of command is typed as double-quote, menuentry, space, single-quote, double-quote.)


Now, going to have you mount the LL root partition in terminal, run a command to confirm the version installed, then unmount it.  Post back with output of these commands also:

Code: [Select]

sudo mount /dev/sda3 /mnt
cat /mnt/etc/issue
sudo umount /dev/sda3



P.s.
I edited your prior posts with terminal output to put them in code blocks.  For some reason (unknown to me) lines with the "@" character between "Ray" and "Ray-Kudu-Pro" seem to automatically trigger the forum software to convert the line into something referring to a member with username "Ray".  Just ignore that -- it's a glitch in forum software design ... a very annoying glitch (to me at least).

Well something went wrong..When I try to boot Linux-lite nothing happens for thr first and second try On the third try it boots Ubuntu.
I insralled grub boot to the sda3 parimeter
I ran update-grub and showed a bunch of kernels and also it stated a configutation file
When booting linux Linux a message came on screen to small and too fast to read or copy
Grub menu continues to show 2.8 on sda3
Any thing I can show you to help

[gold_finger]

You do use the ISO file you downloaded, but you need to burn that to a DVD or USB in order to boot computer with it and install.  In your LL2.8 installation you can use the xfburn program to burn the ISO as an "image" to a DVD; or you can use the dd command in a terminal to make a live USB from the ISO file.  (See the Help Manual for dd command instructions.)

Is parted more accurate than gparted or is it only preference

You can look at partitions in GParted if you prefer that to entering terminal command.  It will show same info as parted command -- eg.  what is shown as /dev/sda3 with parted will also show as /dev/sda3 in GParted.  (I just happen to prefer terminal commands myself.)

[phil66]

Thanks for the install procedure,question why does ll-3.4 require a usb/dvd to install rather than using the iso which I downloaded and ran md5 to verify
Is parted more accurate than gparted or is it only preference

[gold_finger]

Okay, fairly simple process.  If you have anything on LL2.8 that you want saved, copy it off to USB stick or external drive first.


Boot with live LL3.4 USB/DVD.  Before starting install, open a terminal and run the sudo parted --list command to confirm that partitions are still called the same thing as shown in your post above.  (Partition numbering is a bit strange -- starts with sda2 instead of sda1 -- but sometimes that happens.  So you'll want to confirm that current LL2.8 root partition is still called sda3.  If the numbering is different, you'll know the LL2.8 partition by its "Type" -- it's the only "primary" partition.)


Start the installer and choose the "Something Else" install method.  That will bring you to a partition selection page.  Highlight the old LL2.8 root partition, click the "Change" button and in the pop-up box do:

• Use as = Ext4 file system
• Size = leave as it already is -- no change
• Mount point = / (for root)
• Check the box to Format the partition
• Done  (If installer complains that you changed size of partition, even though you did not, ignore message and hit the "Go back" button.  All will be fine.)

No need to do anything with Swap partition.  Installer will automatically see and use that.


IMPORTANT:  Near bottom, set "Device for boot loader installation" = the LL3.4 root partition (eg. /dev/sda3) instead of the default of /dev/sda.  (Assuming Ubuntu was installed after LL2.8 and you did not manually divert boot loader installation for it, Ubuntu's grub is currently controlling boot process because its grub is set in the MBR --  /dev/sda.  So, to keep things as they are don't install LL3.4's grub to /dev/sda.)


Finish install once all of above is set.


When done shutdown/reboot without live USB/DVD.


Boot first into Ubuntu, not LL.  (The grub listing for LL will not work yet because it will still be looking for LL2.8.)  Open a terminal in Ubuntu and run this command to update grub so it finds the new LL3.4 and adjusts the menu accordingly:

Code: [Select]

sudo update-grub

Close terminal, reboot computer and listing for LL should now boot you into the new LL3.4 installation.
