How to restore the Ubuntu/XP/Vista/7 bootloader (Updated for Ubuntu
9.10)


This How-to is for windows dual booters who reinstall an operating
system only to find that it has taken away access to their other
operating system. 

Whether you want to restore the XP, Vista, 7 or Ubuntu (Grub)
bootloader, this guide will walk you through it.


All three parts of this tutorial require that you boot from a cd. If you
don't know how to do this, check here.


If you have made a mistake and want to revert the changes, simply follow
the instructions for reinstalling the previous bootloader. For example,
if you have installed vista over ubuntu, try to get the ubuntu
bootloader back, but want to get the vista bootloader back, simply
follow my instructions for installing the vista bootloader.



How to restore the Ubuntu grub bootloader (9.10 and beyond)


First you need to find out what your drives are called. You can do this
by going to a terminal and typing: 


Code:

sudo fdisk -l


>From that you need to find the device name of your Ubuntu drive,
something like “/dev/sda5″.

So, still in the terminal, type:


Code:

sudo mkdir /media/sda5

sudo mount /dev/sda5 /media/sda5


And then, to reinstall the grub: 

Code:

sudo grub-install --root-directory=/media/sda5 /dev/sda


Push enter and you’re done! Of course you need to replace “/dev/sda5″
and “/dev/sda” with what you found in the fdisk output.
