you can access your linux partition from windows, i never have before so dont know how, maybe someone can help you with that.
to view your windows/NTFS partitions in linux, open up a terminal and type "mount /dev/hda1 /mnt/windows -t ntfs -r -o umask=000", log in as su first. replace "/dev/hda1" with your partition you want to mount, and "/mnt/windows" with a folder, where you want to mount it (make sure to create it first, mkdir /mnt/windows
this is what i do, but it allows only read access. you can switch "-r" with "-w" to allow write access, but i havent tried, if it works let me know.
