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:

Re: Remove 2.8 and dual boot 3.4 with Ubuntu - gold_finger - 07-01-2017
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:
sudo chmod 755 /etc/grub.d/30_os-proberNow run command to update grub:
Code:
sudo update-grubReboot 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:
cat /etc/grub.d/40_customRe: Remove 2.8 and dual boot 3.4 with Ubuntu - phil66 - 07-02-2017

Re: Remove 2.8 and dual boot 3.4 with Ubuntu - gold_finger - 07-02-2017
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:
gksu gedit /etc/grub.d/40_customIn the opened file, delete everything after the line: # the 'exec tail' line above. You should then only have this in the file:
Code:
#!/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:
sudo update-grubNow you should only have Ubuntu and LL3.4 choices for booting in grub menu and Ubuntu will be first (default) choice.
Re: Remove 2.8 and dual boot 3.4 with Ubuntu - phil66 - 07-02-2017
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
Re: Remove 2.8 and dual boot 3.4 with Ubuntu - gold_finger - 07-02-2017
I'm not familiar with program you mentioned for resetting password. You can try to use it and if it works, great. Otherwise, you can follow this tutorial to reset your password. Tutorial is for Mint, but will work same way in LL.
Reset lost/forgotten/non-working Password
P.s.
Before trying to reset password, double-check that you didn't accidentally enable the <CapsLock> key before you tried entering password. Passwords are case-sensitive, so that would cause it to fail if you accidentally hit it.
Re: Remove 2.8 and dual boot 3.4 with Ubuntu - phil66 - 07-03-2017
Tried both reset password programs..The only difference is one spells passwd and the other spells password
Using passwd both units entering password twice and confirming password was completed
In the ll3.4 when opening with e and erasing ro splash quiet $ vt-handoff and adding rw init=/bin/bash
after unable to use password went back to where I made the change and ro splash quiet $ vt-handoff was in the edit of ll3.4
