Running three OSs plus Knoppix on an AMD64-based machine with 3 large SATA drives, onr allocated to each system -- currently XP Prox64, Debian, and Ubuntu -- I started out with XP, Fedora, and Ubuntu. When I upgraded Ubuntu it correctly modified the GRUB bootloader, but when I upgraded Fedora to 9 it failed to recognize and incorporate the other operating systems. My goal with this circus is to identify a Linux or Unix based system I will be happy with as a replacement for Microsoft when they quit supporting XP, which is as far as I'm willing to go with them on my home/office workstation (a very small and neglected market). Anyone know if Fedora 10 will play nice with XP and Ubuntu via GRUB? I gave up on SUSE, which seems determined to have the whole machine or nothing; but I would like to get a little more experience with Fedora. I still have freeBSD and Solaris on my list as well. I always ran Red Hat with my Windows system at home until they split off Fedora and went for the corporate market, and I have worked in Windows, MacIntosh, and Solaris shops -- so now that I am in my Golden Years I do know what I am groping toward. Sort of. Thanks, rmbdick
