Yes you can, as long as you can take hold of your hard drive.
You may use your live CD installer and install grub into the root and MBR partitions using grub command. Since we do not know of your current hardisk map I cannot give any further details of command sequence. However, it is more helpful to you if you 'd become more familiar with the solution by reading a short but good tutorial for grub, read it here
. I assure you, you will control grub after reading it.
Hope this helps.
