if u can boot in linux ..downlaod appropriate rpm from here
install it ..
then issue these commands
see ur partition table and recognize which is ntfs partition .. something like /dev/hdaX
then issue this command ..
# mount -t ntfs -r /dev/hdaX /mnt/winxp
here there shud be a folder named winxp in /mnt
-r parameters specify that its read only ... u cant write to this partition .. n dont even try to .... its not safe
u can make backup .. if u want !!
all the best
