Which linux you are using ?..
If it is debian then you can do it using apt-get ie. online automatic update.
You will understand the following if you are using debian ...
Do..
apt-get install grub
grub-install /dev/hda
# Go edit/make a menu.lst file and put it in /boot/grub/menu.lst
grub
# then on the grub prompt run:
# The partition that has the boot partition root (hd0,0) install /grub/stage1 (hd0) /grub/stage2 p /grub/menu.lst quit
For RPM supported distro..
Get the rpm (use search) and then.
$ rpm -ivh /grubrpmpath/grub-xx.xx.x.rpm
And installing from source ..
$ tar jxvf /pathway/grub.tar.bz2
or
$ tar zxvf /pathway/grub.tar.gz
$ cd /grub-0.9.5
$ ./configure && make install
and in last (you can also move to last step instead of this one[/code]
# The partition that has the boot partition root (hd0,0) install /grub/stage1 (hd0) /grub/stage2 p /grub/menu.lst quit
or simply instead of that..
grub-install /dev/hda
