Laptop boot issue

Postby denzil on Mon Jun 25, 2012 2:24 pm

Running LM11 on a Samsung NC10 with a 60GB SSD. it has been running fine for some time, but this eveing it boots to a text screen

Code: Select all
BusyBox v1.17.1 (Ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash)
Enter 'help' for a list of commands.

(initramfs)


If I restart in recovery mode, the last line before the prompt above is

Code: Select all
No init found. Try passing init=bootarg.


What's happened, and how do I fix it? OK, I could just reinstalling Mint, but I'd like to understand what has happened.

It does not find the root partition. The reason can be a corrupted filesystem, so you could run fsck via liveCD or USB.

sudo blkid # tells the media
sudo fsck /dev/sdxy # where x=HD and y=partition

Seems fsck is not included on the LM13 liveDVD :roll: . Now going to find another distro with it on.

I guessed that, but all I get when I type fsck at a command prompt is

Code: Select all
fsck from util-linux-ng 2.16.1


I am now trying Knoppix from a USB stick, and get the same thing. I have tried fsck -A, but get the same response. I can't make sense of the man page - what am I doing wrong?

An example: If you want to check a partition sda1, it goes like this:
sudo fsck /dev/sda1

Be sure that the partition is not mounted when you run fsck. Command mount tells mounted partitions and devices.

PS. Knoppix may use root user, so it goes like this:
su
fsck /dev/sda1

Thank you, that worked... but so many errors! I spent a few minutes with my finger stuck on the y key. fsck did its best to fix it all, but I now I get "unable to open session" when I enter my log in password. It all seems to be implying a hard drive failure, so it looks like a new one is in order.

You can save your finger if you give a command sudo fsck -fyc /dev/sdxy

Anyway it sounds that your hard drive´s warranty has expired .. :(
