Kai: There was an earlier installation with Fedora Core or CentOS, and
Windows 98 on it.. I think that I wiped the drive, before installing Win
XP and CentOS 5, but that was almost 6 months ago and I am not 100%
positive that I did in fact wipe the HD. For the earlier Linux
installations, I did the partitioning manually, with Disk Druid.

I will reread this entire thread and then keep my fingers crossed and do
it. If I make her system unbootable, my wife will be unhappy......

Thank you, for all of the time and expertise you have shared with me!
