I think I can tell what was going on but not sure if I will explain that correctly.
Before Upgrading Lubuntu 11.10 32bit to 12.04, everything was OK. After each installation to any OS, I run GRUB Customizer (of course after updating GRUB) and rename the entry for the new OS.
As you know, sometimes, the upgrade from release to a newer release will affect some applications. I have checked the repositories and GRUB Customizer PPA was disabled.
1- Why there was many entries for Ubuntu 11.10?
that is a mini Ubuntu installation that had some errors and connection loss and after I was done from that installation, updating GRUB created many entries even before the upgrade.
>> I have formatted sda11 - I don't need that right now. I may re-install ubuntu mini later if I need to do some tests, etc.
Code:
Ubuntu 11.10 (11.10) (on /dev/sda11)
Ubuntu 11.10 (11.10) (on /dev/sda11)
Ubuntu 11.10 (11.10) (on /dev/sda11)
Ubuntu 11.10 (11.10) (on /dev/sda11)
Ubuntu 11.10 (11.10) (on /dev/sda11)
Are gone.
2- Why there was a duplicate?
Looks like after the upgrade (and it seems I chose the wrong option during the upgrade when it asked me about GRUB), updating grub created another entries for each installation + the old entries which I have renamed myself using GRUB Customizer was there too.
I have noticed when it says:
Code:
Ubuntu, with Linux 3.0.0-17-generic (on /dev/sda16)
That is the default entry before renaming it by GRUB Customizer to:
Code:
Lubuntu 11.10 64bit, with Linux 3.0.0-17-generic (on /dev/sda16)
Both exist and that's made the duplicate.
And same goes to the other entries for the other systems.
Still can't tell what 'exactly' happened but at least it's a bit clear now.
>> Now, everything is back to normal without any duplication after I installed Lubuntu 12.04 64bit on /dev/sda15 and I chose to install GRUB to the MBR so now, the OS on sda1 is no longer my main OS.
3- The problem I had before which we discussed here:
http://ubuntuforums.org/showthread.p...195275&page=84
is back again but I followed the same step and fixed it.
Thank you all for your time
