How to Solve Error:File System missing grub rescue error after Installing Ubuntu 12.04 

This one of the issue we faced for a long time.This problem arise due to many reasons.It may due to Damaged Grub boot loader or due to Directory.If Boot loader installed on different  Hard Disk or USB Disk other than your Ubuntu installed Disk ,this problem will arise.In our computer first one happened.We installed Ubuntu many time and delete Ubuntu many time.Our computer has Guid parttion index(GPI) which is available in all new Computer's.This partition is good because all Boot loaders ,Windows or Ubuntu will installed in a particular part of the Disk.So you can remove any OS without affecting other.In ordinary computer after installing Ubuntu,it Grub boot loader will replace existing Boot loader (Windows or other Linux Boot loader).So you need Ubuntu to access your old OS.If something happened to your Ubuntu you won't be able to use your old Os.But GPI partion there is no problem like this.
