Boot Loader - error 15
I have installed Ubuntu 11.10 on my system, previously i was using Windows XP.
I have installed Ubuntu on the same drive where XP was.
Now I have only one OS i.e. Ubuntu.
The problem is that,
whenever i boot, i get an boot loader error 15.
i have searched for the solution,
so i came to know about /boot/grub/menu.lst file, which is not present on my machine.
Please, help me to repair current boot loader settings, or
tell me how to re-install boot loader.
