I can't boot into a usable system anymore. What should I do?
I installed Ubuntu on a laptop's hard drive along with Microsoft Vista. It was working perfectly, but a few days ago it stopped working. I do not know what has happened....on starting it is showing the following screen:
GNU GRUB VERSION 1.99-12ubuntu5...... MINIMAL BASH-LIKE line editing is supported. FOR THE FIRST WORD, TAB LISTS POSSIBLE COMMAND COMPLETIONS. ANYWHERE ELSE TAB POSSIBLE DEVICE OR FILE COMPLETIONS. GRUB>
