This is to be done
when you need to recover the Linux boot loader after another OS has
erased the previous boot loader
most of the Linux distros have rescue mode
lookout for that option when you boot from the 1st Cd of that distro.
you will end up at some shell prompt with some directions about your
current system image
you can follow those instructions to recover the Linux loader
this document will help you to recover the Linux loader for any distro
and any version
boot from a Linux rescue CD or any Live CD
when you are at the shell prompt
run this
#fdisk -l
you will get some entry like this
Device
Boot
Start
End Blocks Id System
/dev/hda1

since i have multiple Linux FS partitions so i have more than one entry
here,
this may not be the case for you ,or if it is then you need to identify
your root (/) partition
Bow i know that my root(/) for my Linux installation is /dev/hda3
so i will make a dir in anywhere ,say in the /tmp directory
# mkdir /tmp/mnt
then mount your Linux installation there
# mount /dev/hda3 /tmp/mnt/
then chroot to that partition
if everything is right then you will end up here
# chroot /tmp/mnt/
root@gaurav/ #
most Linux rescue modes will leave you to this stage ,so the below
directions are common for all distros.
then if you had grub installed earlier the go for re-installing grub as
# grub-install /dev/hda
or if you have lilo installed
you can check lilo installation by
# lilo -v
this will only check if the lilo boot loader will be
installed without any errors and will not install lilo.
and to install lilo
run
#lilo
after this u can exit from the Linux rescue mode and
go for a reboot .
