| + | Add to ''/etc/grub.d/40_custom'': <file> | ||
| + | menuentry "Slackware 14 install (DVD)" { | ||
| + | insmod loopback | ||
| + | insmod iso9660 | ||
| + | set isofile="/slackware64-14.0-install-dvd.iso" | ||

| + | <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. | ||
