Ross: You suspect that I have more than one Linux distro installed, but that is not true. There are 2 OS installed: (a) MS Windows XP Home Edition (the installation of that did not go well on the box with this problem) and (b) CentOS 5. After I wiped the HDs in the 3 boxes, last Thanksgiving weekend, each of them got a /boot partition of approximately 100 MB. If you have any ideas that are non destructive, please let me know what they are. If this problem was on my box or my daughters box, worst case is I would "learn by destroying" and need to wipe the HD and start over. However, this is on my wife's box and if I screw it up, I have problems with her. :-) TIA, Lanny > I would typically have /dev/hda1 setup as a 256MB 'boot' and reuse it > for other distros, just make sure not to format it on install or you'll > bork the first distro's kernels! > > -Ross _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
