For normal hdd installation:
apt-get install grub
/sbin/grub-install /dev/hda
update-grub
Then check /boot/grub/menu.lst and edit to your requirement.

But for your system, that procedure, I don't think will work since you are using poorman hdd install. Apt-get will not work so do with installation of other application from source code. Unless you use klik and point.

Your option is to use Grub for Dos.

Don't ask me how because I never use it.
Check on post title ISO boot from NTFS (GRUB.exe, grldr from boot.ini)
