Remember, if Windows is on an NTFS partition, it's best not to make that one writeable. If you have a writeable partition upon which you want to save the Windows data, you will have to select the option to mount it read/write as opposed to the default, which is read-only. Right click on the icon for the partition and be sure that read-only is not checked and remount.

If you need access as root, do "sudo passwd" to change the root password to one you know, then you can "su" and change to root.

If you're going to save it over the network, use linneighborhood to mount the network share locally.
