I am running Windows XP on my first disk which is hda (0,0). I have both Ubuntu and Mandriva on the second disk which is hdb (1,0) and hdb (1,1). Whichever Linux OS I load grub does not see the other Linux OS. My Windows runs fine and which ever Linux OS I loaded last runs fine. How can I get both Linux OS's running and keep Windows as the defalult on the first disk? Please be as specific as you can as I am a newbie.
