GRUB after-install Fix
Linux beginners with existing Windows XP/2000 systems often install GRUB straight into the partition instead of putting it into the MBR, with the result that the system starts, but contains only Windows. Access to the Kanotix OS is therefore not possible without creating a boot floppy.
Solution:
Boot with the Kanotix
LiveCD, then mount the Kanotix system partition, for example
hda3?, from a console or terminal:
su
mount /media/
hda3?
Then reinstall GRUB:
grub-install --recheck --no-floppy --root-directory=/media/
hda3? /dev/hda
which installs it into the MBR.
(for KANOTIX's version 2005-03 or older use mnt instead of media)
