    Can't boot 2.6.31-19-generic

    Hello, all.

    I'm running 9.10 and I'm having a real hard time loading the new 2.6.31-19-generic kernel from the grub2 boot menu. Whenever I try to load it, it responds with the following error:

    "error: You need to load the kernel first.

    Press any key to continue..."

    It then just kicks me right back to the boot menu. I checked the grub.cfg file and everything seems to check out and I also checked the settings in grub (pressing 'e' with 2.6.31-19-generic selected...I'm still pretty new with ubuntu, so forgive my simplicity). I also made sure the file "vmlinuz-2.6.31-19-generic" is in the boot folder. I also tried manually booting from the grub2 command line using:

    Code:
    sh:grub>linux /boot/vmlinuz-2.6.31-19-generic root=/dev/sda2 loop=/ubuntu/disks/root.disk ro
    sh:grub>initrd /boot/initrd.img-2.6.31-19-generic
    sh:grub>boot
    I might be missing something obvious, but I'm not sure. As I said, I'm still fairly new with Ubuntu (I love it!), so any help with this would be greatly appreciated!

    Thanks!

    The only kernel I'm actually able to run is 2.6.31-14-generic...so I'm quite a ways back.

    Beginner question: Is there any notable/important updates from kernel to kernel?

    I guess I can forget about all of this...had to reformat and reinstall.

    Why?

    Anyway you should have a look at this:

    Re: Can't boot 2.6.31-19-generic

    Hi everyone,

    I upgrade to -19 kernel and as a lots of people ran through troubles...
    After launching my computer and choosing ubuntu from the computer display immediatly the grub1.97~BETA4 SHELL
    No booting for me too
    I've read like 50 pages and figured that going back too -17 was a solution very fine for me.
    so I've looked for a detailed process (found here )
    applied it but I continuously get a message like 'the magical number is invalid'.
    I think the root directory is "broken"...
    for root=/dev/sd** the directory simply doesn't exist

    to check my partition I did
    Code:
    sh:grub> ls -l
    and got info on device loop0, UUID
    Device hd0, partition hd0,1, type ntfs,UUID

    nothing more when I checked the mapdevice file partion are suposed to be maped in /dev/sda

    but in /dev there isn't any sd** file

    ...... so don't know what to do next...

    And one last thing here:

    Code:
    loop=/ubuntu/disks/root.disk ro
    IF /ubuntu is supposed to be an existing directory, this is not here too....

    Thanks in advance, great forum !
    bye

    Try booting into an older kernel version and then run in terminal (updates the grub.cfg file):
    Code:
    sudo update-grub2
    Reboot and try new kernel again.

    If that doesn't work, reboot into the old kernel version and run this command in terminal:
    Code:
    sudo apt-get --reinstall linux-headers-2.6.31-19 linux-headers-2.6.31-19-generic linux-image-2.6.31-19-generic && sudo update-grub2
    Apart from those, have no other suggestions other than to completely remove the newest kernel version and attempt an update again.
    Never had to do this before though, so someone may want to clarify a little more.

    IF /ubuntu is supposed to be an existing directory, this is not here too....
    "/ubuntu" is supposed to a directory on your "C:" drive (or whatever drive is containing your Wubi file)

    I suggest to first follow these instructions:
    http://sourceforge.net/apps/mediawik...lems:Wubi_9.10

    It cures almost all Wubi boot problems caused by updates.

    If this does not work, and reinstalling the kernels also did not help, please follow these instructions to run boot info script and post the "RESULTS.txt"

    Great find as well. Thank you. As per the wiki, I updated the wubild file on c:\ and 2.6.31-19 generic was then fine. Nice wiki, and thank you.

    My first post!
