pardon if I posted this before. I was working on grub last night. Win2k and Fedora 7 are on sda (hda) while FC3 is on sdb (hdb). The MBR on sda is being used, I believe. Which grub do I edit to get all OS's booting? I tried a few variations, mucking with the one in /boot/grub/... from FC3, but wasn't able to hit on the correct combination.
