    Darn! It does look like there was something in that partition table causing the problem, but to figure out what, we need a copy of it, which you have destroyed ;(

    Thanks for this and all your grub tutorials (from your signature)
    I found the chainload one useful

    Do you have any one on setting up multi-boot systems?

    It is pretty well automated in grub2: it just detects the other systems and adds them to the menu.

    If you want a nice background for grub2 as well and a simple dual boot menu that you will never have to mess with,
    you could check out the tutorial in my signature.

    It is listed on page one step 19 in this tutorial.

    linuxbasiccommand,

    Thanks. I edited your post to remove quoting the entire first post of the thread. Don't know if it was intentional on your part but if anyone needs to refer to it they can click on the First link to the lower right of the last post on this page.

    Re: Grub 2 Basics

    Psusi and Cavsfan:

    The automated multiboot detection works when the two OSes are not 'symmetrical.' A typical example of this would be: I have Meerkat on sda5 and Karmic on sda6.
    In this case I let Meerkat own grub, mbr etc and detect (and point to) Karmic. In effect Karmic is 'parasitic' ie it is not updated and lets itself get 'managed' by the Meerkat install.

    However this gets messy when the multi-OSes are both live and regularly updated, say Meerkat and Debian sid. In this case when one updates 'automatically' it stomps on the other's toes.
    I asked this on the grub list and got useful answers from Jordan Uggla
    thread here

    Since DRS has written some nice grub tutorials I thought he may want to give configfile and multiboot options more public visibility in place of the older chainload.

    [For the record the suxware state of the grub2 docs can be seen if you try to click some of the options at http://grub.enbug.org/CommandList]

    I did some exploring the library files and others... no changes I attempted to make appeared in the G2 title.
    Did anybody find a way to edit the list of systems boot options?
    I have updated so may times and grub2 keeps putting the options on the screen, that the second OS option is in out of the screen to choose!

    I need/want to remove at least 4 kernel options from the boot list (kernel versions I removed, since I use only the last, after every update).

    Thanks and sorry if there is a answer to this somewhere else and I didn't find it.

    Gonzalo_VCk,

    There are various ways to trim the menu, if that is what you are asking. The easiest way to remove older kernels is via the GUI app "Ubuntu-Tweak".
    Here is a guide on how to remove kernels, including instructions on Ubuntu Tweak:
    HOWTO: Remove Older Kernels via GUI

    You can also customize things via Grub Customizer. It can hide the older kernels but doesn't phyiscally remove them. The link is in my signature line.

    Re: Grub 2 Basics

    THANKS! It worked perfectly.


    PS: the older kernels are removed by apt-get autoremove, that I apply after apt-get upgrade, if I am not mistaken.
