    A side of there are old Kernels,the menu is duplicated:

    You can houseclean old kernels in each install to reduce entries.
    Yes my good friend, I'm aware of this but the duplication (I don't know what happened - I'm interested to find out), IMHO, must be fixed first or I could be wrong about this.

    But if repeated, it may be a script issue in os-prober of some sort? We have seen where a user created multiple copies of some scripts.
    I never ever use any script
    Everything was fine "before" the upgrade from Lubuntu 11.10 to Lubuntu 12.04 and I'm not exactly blaming the upgrade itself, but ... could be something happened to the GRUB Customizer? because I used to "Hide" the older Kernel using GRUB Customizer so that explains why the old Kernels are showing up again. However, that doesn't explain, IMHO, the duplication.

    I like to keep two as a minimum.
    Same here


    If you want to try 40_custom you can add just one of your other Ubuntu entires with this. pick the partition number and edit partition number and label. I think cavsfan link has more detail.

    gksudo gedit /etc/grub.d/40_custom
    Then do:
    sudo update-grub

    I first saw this from Ranch hand
    Note that this does not define the kernel. It defines the partition. It boots the newest bootable kernel that it finds at that partition. example based on sda13 change all 13's to your partition number.

    menuentry "Ubuntu on sda13" {
    set root=(hd0,13)
    linux /vmlinuz root=/dev/sda13 ro quiet splash
    initrd /initrd.img
    }

    If that boots your install in any of your partitions, then we can add all your other installs, and turn off os-prober. Then you only have one entry per install.
    Before I try that, does GRUB Customizer offer such feature or process? for me, I have two test machines with Multi-Booting Systems (not less than 6 systems minimum) and GRUB Customizer is a great tool to save time. I'd love to improve my skills with editing GRUB,etc but I don't have much time these days

    Thanks a lot, oldfred for your help ... I'd like to find out what is going on with the duplication

    P.S.
    @Cavsfan
    I may try that but first, I need to know the answer for my Qs above
    Thanks a lot

    amjjawad, what does this produce entered in terminal:
    Code:
    grep menuentry /boot/grub/grub.cfg | cut -b 1-11 --complement | cut -d "'" -f1 | cut -d "\"" -f 1 | nl --starting-line-number=0

    Re: Grub 2 Basics

    amjjawad,

    The multip le entries may be coming from Grub2 'mining' information from other Grub menus. In other words, when Grub updates, it searches all the other partitions for bootable kernels and from Grub-readable menus.

    It will look for grub.cfg and menu.lst files and can extract entries from those.

    When I was troubleshooting this type of problem, I first looked at grub.cfg to see if all the duplicates were located in the 30_os-prober section. If so, I then looked at those partitions (based on the entry) to see what kind of old (or current) menus might be found by grub.

    As a test, I would rename an entry in those menus and then run update-grub to see if the new name appeared in grub.cfg. For instance, I'd rename an entry "Ubuntu..." to "UUbuntu".

    And don't forget if you use variations of Ubuntu (Mint, etc) the kernel title may be the same as that of your Ubuntu OS. I am not sure what the current policy is, but a while ago most of the variations still showed up as "Ubuntu, ..." even if it was really a Kubuntu installation, etc. Don't use those distros so I don't know if that is still the case.

    By the way, the execution of this commend:
    Code:
    sudo grub-mkconfig
    ... is by far, the SLOWEST ever :/
    I don't know, perhaps because I have tons of installed systems? or it's a problem somewhere else? even updating GRUB takes SO long on this machine.

    Yes, the HDD is IDE but, as far as I can tell, it never was that slow before. My guess it's because of the systems I have installed. Slow when it comes to the execution of commands like
    Code:
    sudo update-grub
    which takes 2mins and 58secs ... just checked that on a stopwatch on my phone.

    Yes my friend drs305, it is still the case until now. As long as the system (distro) shares the same core as Ubuntu, it will shows as "Ubuntu" not as "Lubuntu" or "Xubuntu" unless you rename it and I always do that after I'm done with installation and I use GRUB Customizer for that to make my life easier.

    This might not be the same case but I think it's for the same reason (all Ubuntu variants share the same core), there is this bug: https://bugs.launchpad.net/ubuntu/+s...er/+bug/990091

    and my comment here already states that: https://bugs.launchpad.net/ubuntu/+s...091/comments/2

    I have posted the output of the commends on my previous post. This might enlighten us to find out what is wrong?

    Re: Grub 2 Basics

    I hope this helps. I figure this out: I counted 60 menu entries!

    Code:
    4  menuentries in 10_linux_proxy
    2  menuentries in 20_memtest86+
    27 menuentries in 30_os-prober
    27 menuentries in 30_os-prober_proxy
    Since the 27 are duplicated in the os-prober files, one way you could get rid of the duplication is this
    sudo chmod -x /etc/grub.d/30_os-prober

    But, we better wait on drs305's insight first and see what he thinks.
    I noticed you don't have a 10_linux file but, have a 10_linux_proxy, 30_os-prober and 30_os-prober_proxy files.

    That is why I posted here

    Re: Grub 2 Basics

    I'm still working on it. I see several duplicates but, not sure what to do. I'll work on it a bit more and see if I can help.

    You are very welcome! This is challenging and I like a challenge. Not sure If I am up to it but I know drs305 is.
    I am hoping I can save him some time and provide some worth while info on your system.

    Actually I got most of my info from ranch hand about writing the How To. I know drs305 as he has helped me many times and I have tried to help
    out when I notice he may be out of town. That is if it is something small that I can understand.
    I have seen oldfred on here a lot helping with grub and I know he knows a lot about dual booting Ubuntu and windows too.
    This is a very good forum!

    Re: Grub 2 Basics

    It would definitely not be right to do this sudo chmod -x /etc/grub.d/30_os-prober.
    It looks like several things are duplicated between 10_linux_proxy, 30_os-prober and 30_os-prober_proxy.
    But, since you cannot edit them I don't know what to do. The following lines are all of the menuentry lines from your grub-mkconfig output.
    This is from the 4 files that have menuentry in them and the blank line denotes end of file.
    Hopefully drs305 can make sense of this data and get to the bottom of this.
    And hopefully all of this is useful to drs305. I am at the end of my ability to help further but, I tried.
