Fix the error “No init found Try passing init bootarg”

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.

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

The system can usually be restarted now.
