Power Macintosh 6100: Converting From SoftWindows to DOS Compatibility Card

I have a Power Macintosh 6100/60 running SoftWindows, and I have now purchased a DOS card. I want to maintain my applications and data files on the SoftWindows partition. PC Setup will recognize the SoftWindows partition, but when I switch to the DOS Compatibility screen I get a message saying, "Missing Operating System". How do I access the SoftWindows partition?
A SoftWindows/Soft PC drive file cannot be used as the C: drive for the DOS Compatibility Card. However, the SoftWindows/Soft PC drive file can be used as the D: drive. The following steps show how to access the that file with the DOS Compatibility Card.
