Just installed Xp Pro. When installation began, disk did not offer "upgrade" option as expected, only "install (advanced)." Was afraid of deleting all Win98 files, so I placed xp pro in a directory with a different name. Now I have a c:\new name with xp pro and a c:\windows with win98. OS works fine but two sets of files have consumed all of my 4.0 gig hard drive and apps not functional. How do I fix this without uninstall/reinstall xp pro? And, if must uninstall/reinstall how to do that? Thanks!
