In most of the systems GRUB is now upgraded to 2.0 and with this update the old restore process have also changed now there is no grub command :) available.
If you have lost the Bootloader after a routine reinstall or due to any other reason try the following to restore
Boot Using a Live CD and try the following as root
grub-setup -d /media/XXXXX/boot/grub -m /media/YYYYY/boot/grub/device.map /dev/sda
