I have a dual boot w98se/wxp. Colonel Kern's advice was sound. Do a websearch.
I reformated my hard drive on a new pc. Installed w98 first, the wxp in a FAT format. The install games under the different os. Its a long process. May take a week or so. But I did it 5 years ago and have never had to recover, reinstall, or even reinstall a game in all that time.
