If a system with Ubuntu Linux does not shut down correctly, but suddenly fails due to a power failure without UPS backup, it can at the next start attempt for error message No init found. Try passing init = bootarg. come. The computer will not start in this case. With a file system check you can usually fix this problem.

problem

When starting the computer, the following error message appears (in the example with Ubuntu 10.10):

solution

A file system check often fixes the problem.

  1. Start from a Linux Live Boot CD or from the TK USB Stick .
  2. Perform a file system check of the boot partition (in this case / dev / sda1):
knoppix @ Microknoppix: ~ $ su -
root @ Microknoppix: ~ # fdisk -l / dev / sda

Disk / dev / sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors / track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical / physical): 512 bytes / 512 bytes
I / O size (minimum / optimal): 512 bytes / 512 bytes
Disk identifier: 0x000d8343

The system can usually be restarted now.
