    updated - now won't boot

    I can't boot now after an update. I'm getting this:

    error: cannot read the linux header
    error: you need to load the kernel first

    Press any key to continue...
    After than it says

    Failed to boot both default and fallback entries
    then it goes to grub and I pick 'previous linux versions' and I can boot into -14

    It's a P-III, 1133Ghz, 512RAM, Dell Laptop
    I have:

    3.0.0-14
    3.0.0-13
    3.0.0-12

    It's been running Lubuntu fine for about six months now. Last night I did the updates and it won't boot.

    I scanned the RAM and the hard drive and they are fine. Then I tried the 'previous version" which is 3.0.0-14 and it works fine. I went into
    /etc/default/grub and changed the video to 640x480 and did 'sudo update-grub' and that worked so I know that's working.

    So, it seems to me that either:
    3.0.0-15 doesn't run on a P-III, or

    3.0.0-15 got corrupt somehow
    How can I uninstall -15 and re-install it, ... or ... where would I need to look to see if -15 stopped supporting P-III's , ... or, can I back out the update somehow?

    thanks

    If you can boot 14
    You should be able mark 15 for re-installation in synaptic
    You should install synaptic if you haven't already!

    Re: updated - now won't boot

    what do I search for to find it?

    headers
    header
    kernel
    3.0.0-15
    linux

    ...

    I'm not really sure what it's called and what all the parts are, though I guess the package manager should get all the parts if I select the main cahuna.

    By "Synaptic" you mean the "Synaptic Package Manager"? ... Yeah, but that came OOB IIRC. I don't think I installed it.

    I searched for "3.0.0-15" and found three that are checked. Are these three enough?

    linux-headers-3.0.0-15
    linux-headers-3.0.0-15-generic
    linux-image-3.0.0-15-generic

    Are you working outside the defaults?
    How were you updating?
