I was using my Dell laptop with Ubuntu 12.04 yesterday just fine. Howerver today it will not boot.

It's getting stuck while booting at stopping system v runlevel compatibility [Ok]. When here the laptop shows that line for about half a second, then the screen goes black, and then it tries again (over and over).

I have now entered recovery mode and gone in to the console. From here I tried to update, just because it's a good thing to try, but I'm being presented with this error

dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

Running the suggested command yields this error -

unable to access dpkg status area: Read-only file system

Can anyone please help me to gwt my laptop working again. Thanks.

In recovery mode the file system is mounted as read-only. Run file system check so it will mounted as read-write. then drop to shell and run sudo dpkg --configure -a. If you want to update, activate network before that. –  Sneetsher Feb 5 '14 at 0:21
