Keep getting the above message on bootup. Other threads indicate using manual recovery then entering "mount-o rw, rw /". However, when I press m for manual recovery I get a "couldn't write bytes, broken pipe" message. then after a while Ubuntu loads up. It's not a major issue, but it means my bootup time is about 4 or 5 minutes as opposed to ~30s. Have recently re-installed 12.04.3 to try to solve it, but happens more frequently than on 12.04.1.

There's tonnes of threads for the 1st problem & equally for the second, but none for the 1st followed by the second. Can anyone help?
