Uhm...It seems you're making some troubles somewhere anyway..why don't you enter in your distros with a live like knoppix or ubuntu or mint or sabayon..see you..burn your files on cds or dvds and then delete all linux partitions? then do a good partitioning with gparted,install windows,make a norton ghost image of windows in case of future problems,then install your first distro by the way i told you before,make an image by partimage,then install your second distro by the way i told you before,make an image by partimage..and hope everything goes well ?everything should take you about 4 hours..you could do it after a dinner..i've done so since 2005 for multiple bootings and have never,never experienced any boot problems !!
I had done a post too with my personal advices in installing...take a look
and IN MY OPINION FEDORA IS SHIT..try installing
mandriva original,not pclinux,and install ubuntu or gentoo or sabayon or knoppix..with the others i've always found some little bugs
Let me know how it goes
Ciao !
