My ultra-book has dual boot of windows 10 and Ubuntu 14.04. It was windows 7 a year ago I just upgrade it to windows 10 a month ago.
It works fine until yesterday. Today I turned it on and went to Ubuntu. The first time it shows it cant open Firefox because it’s running … something like that. So I restart my ultra book. then the error:
error:attempt to read or write outside of disk ‘hd0’.
Press any key to continue.
Then whatever key I pressed it is still the same. The power button does not work either.
I can’t even force to shut it down. what should I do?
Try make a live version of Ubuntu and mounting the partition Ubuntu is on your hard drive. Look go to the file ‘/boot/grub/grub.cfg’ and see if hd0 or a different drive number lives in the code.
You can see what hard drive number your grub.cfg should be on by using gparted.
