Dual installing Ubuntu 13.10 with Windows 7 was successful. I was asked to re-start and when I did it will not reboot. I received error message indication a "folder/drive" does not exist. Then a command prompt dialog "grub rescue>" opened. I have no idea what it is and what commands I should enter.
I tried to re-install Ububtu and it showed that I have both Windows 7 and Ubuntu installed and gave reinstall options. There was no option to delete/remove just Ubuntu.
I am stuck, and need help.
