    12.04LTS: wrong kernel modules installed

    Install seems to have pooched the system. I just installed 12.04LTS over an openSUSE installation on my AMD64 and not much seems to work. Most importantly, the network doesn't work. I think the reason is that the wrong kernel modules are installed. When I type uname -a I get told that the kernel is 3.4.63-44.desktop, but when I look at the contents of /lib/modules all I see is "3.2.0-23-generic".
    I selected the "something else" option in the install, because I didn't want to "install alongside openSUSE" nor did I want to do a fresh install that seemed to promise to wipe out my home directory! So I choose something else, then simply selected the old root partition as my root partition and the old home partition as my home partition. All these file systems are ext4 and I didn't opt to format anything. Well, when I started it, I found that installing the proprietary nVidia drivers didn't work and that's probably because the network didn't work. I was unable to get any network action (no sign of Ethernet life when I typed ifconfig -a) and when I tried modproble r8169, it gave me some sort of error about module misconfiguration. That's when I realized I had the wrong modules.
    Oh another thing: I don't get a boot menu. At first I get the openSUSE splash screen for a split second, then Ubuntu starts. I'll bet I could have gotten somewhere if I got a boot menu.
    Unfortunately, I can't figure out how to fix any of these problems by hand.

    Edit: and I'm pretty sure I selected /dev/sda as the device for the "boot loader installation"

    You may now have a mix of an Ubuntu install and a partial OpenSuse install. If it were me, I would backup the data in my /home partition and do a clean install of Ubuntu.

    I'm afraid that's out of the question. My home directory goes into the 100s of Gb. I might be persuaded to format the root, but I would have hoped that the installer would have dealt w/any other distro and made sure it didn't interfere.

    Great... I just made it worse by following the instrunctions from http://www.howopensource.com/2012/05...4-live-cd-usb/ but now I can't even start Ubuntu. I'm going to try it once again, then if that doesn't work, installing again. If someone can give me advice before going that far...

    Actually, using boot-repair again seems to have worked. Now I have a boot menu and can access the 3.2 kernel. I can only assume now that the update will take care of the missing modules issue

    Of course it was a problem of my old installation interfering! I just realized that the 3.4 kernel there has a timestamp from last year, so no doubt it was left over from openSUSE. Loading that by default (for some reason, the bootloader wasn't giving me a choice), the poor thing didn't know what to do w/this new kernel. Now I just have to figure out how to edit the boot menu to get rid of that troublesome selection.

    Whew, good save. I figured there must be remnants of the old install present.

    There are ways to configure Grub2 by hand, but I find it confusing. Try this:
