Before reinstalling the system, move the things that need to be left on disk C to other disks. Do not manually intervene when installing the system. If you don't know when to take out the CD, just wait until the system is installed and it won't change.

Reinstalling the system will only change the system in the computer C disk, such as the files and things in the computer D, E and F disks.
