We assume there are 2 harddiscs in the PC: windows is installed on the first harddisc, and KANOTIX is installed on a partition on the second hd, e.g. on hdb5. Now boot the Live-CD: Open a Terminal and become root with $ sudo root. Mount the partition where Kanotix is installed (in our example hdb5) # mount /media/hdb5 Now rewrite Grub to MBR: # grub-install –recheck –no-floppy –root-directory=/media/hdb5 /dev/hda (for KANOTIX’s version 2005-03 or older use mnt instead of media) That’s it!
