Selecting the “Import partition setup” button will import settings that will reformat your / and more importantly your /home partition.
To resolve this always check your settings for each partition. It will show the “F” (format) next to / and /home partition.
Click on the edit partition button and deselect format the partition. If this is not done you will lose all of your data on your /home partition.
