Since you're transferring OSes, you must use the import/export tool (instead of just copying files) as there's certain filesystem incompatibilities. This will also transfer your FFF configurations.

Thanks for the tips! I tried to export it out of Windows, but it said I am using the portable version and so was not able to do the export. Let me try those links you sent and I'll let you know!
