actually it was in the setup. It will actually recognize NTFS without any problems, but for whatever strange reason, rh won't set lilo/grub to install an entry for NTFS (why i have NO idea!). next time you go through the install, when you come to the boot setup, make sure to give your NTFS partition a label (that will fix it, amazingly). but for now, what you'll need to do is manually add an entry for winXP. what bootloader are you using?
