The MBR did not get updated: still points to XP.  I wonder whether live
Knoppix allows write access to the MBR.

I prefer to re-install MBR by booting grub from a floppy.  My Linux boot
partition is hda3, so:

grub> root (hd0,2)
 Filesystem type is reiserfs, partition type 0x93
grub> setup (hda)
grub> reboot

This doesn't install grub, it just writes the MBR.  You could use 
grub> root (hd1,x)
grub setup (hda)
if your grub boot files are in hdb(x+1).
