Problems appear after installation

[ville.jt.kauppinen]

I have installed 12.04.3 on my mini-laptop (eMachines 350-21G16kk). Everything is fine after installion, but when I reboot the laptop couple of times, nothing works and system cannot mount drives. It won't start even in recovery mode. I haven't installed windows on the hard drive, just ubuntu. How can I fix the problem? I attached picture of error message in this forum post.

I have tried to fix problem with sudo fsck /dev/sda1/ command in live-usb mode. Same problems appears after few reboots.
What should I do next?

Try installing again. But before you do:

Post some details of your computer, RAM, Graphics, CPU etc.
And also Boot with Ubuntu DVD/USB and 'Try Without Installing'. Open Terminal [Ctrl+Alt+T], run the following command and post the output:


sudo parted -l
sudo fdisk -l

Not sure what the problem is with your current install.
Re-installing might help.

A suggestion: Your e-machine specs are a bit low for Ubuntu, consider installing Xubuntu or Lubuntu.

First I tried to install Xubuntu and Lubuntu alongside with Win7 Starter, but same problems appeared (OS didn't started after couple of reboots). Maybe I'll try next clean Xubuntu install without Win7.
