I use HP pavillion dv6. I installed ubuntu 13.10 after using gparted in try version to remove all the partitions from my previous dual boot(windows 7 and ubuntu 12.10). I had to install the new Ubuntu because I've been troubled by the messages like unkown file system, attempt to read or write outside 'hd0', Read error when I boot along with the grub rescue. So now I erased all the data after backup and reinstalled the ubuntu 13.10 to get rid of the above problems. But the problem still persists. Please urgent help needed.After performing boot repair i got a message including the url http://paste.ubuntu.com/7115746/.
