Last night I've updated the Udev Package on my Ubuntu 10.04 (32-bits) and after system restart my PC was unable to boot.

The error messages were the following:

udevadm settle is not permitted while udev is unconfigured
ALERT! /dev/disk/by-uuid/)a8cc71e....071cd does not exist. Dropping to a shell

Was it a plague of St. iGNUcius because I have written an article about Windows?


After some research on Google, I found out the solution:

• Boot the system using the Ubuntu live CD. If Ubuntu automatically mount the hard disk partition, unmount it before proceeding. This can be done easily through Nautilus.
  
  
• Open a command prompt.
  
  
• Create a new folder in order to mount the HD:
  
  
  
  

  sudo mkdir /mnt/newroot
  
  

• Mount the HD (sda1, in my case):
  
  
  
  

  sudo mount /dev/sda1 /mnt/newroot
  
  

• Change the root directory:
  
  
  
  

  sudo chroot /mnt/newroot
  
  

• Run the following command:
  
  
  
  

  update-initramfs -u -k all

  
  
• Return to the old root and unmount the partition:
  
  
  
  

  exit
  sudo umount /mnt/newroot
  
  

• Reboot.

After these steps, Ubuntu should work without problems.
