Hello again, peoples!
I'm sorry it took me so long to remember to come back and thank everyone for their help. rhfrommn was right on the money - the Windows installer will trash everything in sight! Bought the disc (even though it practically made me physically ill to put even another penny into Gates' pockets) and it happily strangled FreeBSD. We are back to two computers for all the homework, games, etc. and I sincerely appreciate that all who helped, took the time to do so. Guess it's kinda sad, though. I would be more than willing to learn to use the FreeBSD, and teach my kids, on a finished computer with this OS, and be free of the Gates scourge. Ah, well.... Thanks again, everyone!
