Fisrt I install Windows XP on my coomputer.and then I install Fedora core2 on my computer in the different partition. During installation of Fedora core2 I recieve a message about an warning on boot loader.If I would cancel the error ,the Fedora could'nt install.So I ignore the error.When I insatll Fedora compeletlly,I see that Windows XP could'nt boot.
See http://www.redhat.com/archives/fedora-devel-list/2004-May/msg00908.html for how to recover from this problem.
