    Exclamation Cannot boot ubuntu after upgrade

    hi,
    Yesterday I do upgrade my ubuntu from upgrade notifier.

    when I restart my system, while booting ubuntu, boot splash screen has been changed to ubuntu 10.04 and four dot below, with low graphic. and after a while I received these messages.

    udevadm trigger is not permitted while udev is unconfigured
    udevadm settle is not permitted while udev is unconfigured
    udevadm settle is not permitted while udev is unconfigured
    udevadm settle is not permitted while udev is unconfigured
    /script/init-top/console-setup: .: line 18: can't open /etc/default/console-setup
    ALERT! /dev/disk/by-uuid/87b9b1b3-0b82-4f19-bbb6-73d3cd7f71ca does not exist. Dropping to a shell!

    BusyBox v1.13.3 (ubuntu 1:1.13.3-1ubuntu11) built in shell (ash)
    Enter 'help' for a list of built-in commands.

    (initramfs)
    I try to boot recovery mode, but I get the same messages.
    I read other topics, but they didn't solve my problem!

    what should I do

    -----------
    additional information:
    ubuntu version: 10.04 lucid lynx
    GNU GRUB version: 1.98-1ubuntu5
    dual boot with Win7

    Let's see if it's just a bad fstab entry or something more severe...

    Boot to a LiveCD.

    Mount your Ubuntu partition. If you don't know which one it is, run these commands. If you still don't know, post the results (the second one is a lowercase L):
    Code:
    sudo blkid
    fdisk -l
    To mount (Substitute XY for your partition, such as sda1, sda5, etc):
    Code:
    sudo mount /dev/sdXY /mnt
    Open fstab for editing:
    Code:
    gksudo gedit /mnt/etc/fstab
    Look for an entry with "87b9b1b3-0b82-4f19-bbb6-73d3cd7f71ca".
    If it is the listing for /, change the first part of the line:
    UUID=87b9b1b3-0b82-4f19-bbb6-73d3cd7f71ca
    to:
    /dev/sdXY
    If it isn't / or /home, just put a comment symbol (#) at the start of the line, like this:
    # UUID=87b9b1b3-0b82-4f19-bbb6-73d3cd7f71ca
    Save the file and see if it now boots.
    GRUB2

    Retired.

    For those concerned
    Code:
    # /etc/fstab: static file system information.
    #
    # Use 'blkid -o value -s UUID' to print the universally unique identifier
    # for a device; this may be used with UUID= as a more robust way to name
    # devices that works even if disks are added and removed. See fstab(5).
    #
    # <file system> <mount point>   <type>  <options>       <dump>  <pass>
    proc       /proc           proc  nodev,noexec,nosuid  0  0  
    /dev/sda5  /               ext4  errors=remount-ro    0  1  
    /dev/sda6  none            swap  sw                   0  0  
    /dev/sda4  /media/Windows  ntfs  defaults             0  0  
    /dev/sda7  /media/Bridge   ntfs  defaults             0  0  
    /dev/sda2  /media/Store    ntfs  defaults             0  0

    You don't just run commands to fix anything until you have correctly identified the problem.

    I mentioned what I did so you could have a look (I expected you to do a forum search after I mentioned seeing a recent thread) and see if it was related. Here is the link:
