you have grub2 installed windows ntfs partition boot sector. has contain windows boot code part of winodws booting.

have /boot/grub files/folders in root of xp. can delete those. think win7 has /boot folder can confused /boot windows not case sensitive.

fix most, few have other issues, better windows fix in many cases fixes other parameters:
has instructions on using testdisk repair install of grub boot sector windows ubuntu or linux livecd.
http://sourceforge.net/apps/mediawik...ms:boot_sector

can run windows fixboot command if backup destroyed also.
