How to Fix Grub After Windows
Grub (which stands for GRand Unified Bootloader) is a program that allows you to choose booting between a number of different operating systems installed on one computer. For example, you could have Ubuntu Linux and Windows XP installed on the same machine. Unfortunately, if you install an operating system such as Windows AFTER you install Linux, the Windows installation will wipe out your grub loader, leaving your Linux installation inoperable. Fortunately, it's easy to fix grub after windows with the help of a program called Super Grub.
