+<note>(hd0,2) means "//the second partition on the first drive//" (i.e. ''/dev/sda2''). You can find the right value in the "''set root''" command of the menu entry used to boot your system, or else consult with [[http://www.gnu.org/software/grub/manual/grub.html|GRUB manual]]. </note>
+Then update grub with: <file>
+ grub-mkconfig -o /boot/grub/grub.cfg
+</file>
+<note>On Slackware before running grub-mkconfig you have to run ln -s /dev/sda2 /dev/root
+where for sda2 you have to enter your root device.
