Here is how I did it with my Mandrake set-up:
You add these lines to the /boot/grub/menu.lst file. Grub uses a slightly different numbering system to refer to the various parts, as the numbering begins with zero, not one. "hd0" referrs to hda. The "0" after the comma would refer to the first primary part. The numbers are one less than the part nos. Since 'Drake has its root part on /dev/hda5, the corresponding menu item is "root (hd0,4)". Thus, to boot Winders on your rig, try: "root (hd0,2)". You can get a good idea as to what to add to your menu.lst file by studying what's there already. Also, be sure to make a backup copy
before you start hacking on it. I've never had anything go wrong, but you can't be too careful where system-critical files are concerned.
