+9. Decrypt your partition. After decrypting you may assign mount points:
+   Open the Unknown list and select `qubes_dom0-root`. Check the reformat box to the right and choose `ext4` as a filesystem. Enter `/` into the Mount Point field at the top.
+   Repeat the process for `sda1` and `qubes_dom0-swap`. Those should be assigned to `/boot` and `swap` respectively.
+   The default file systems are ext4 for `/boot` and `/`, and swap for `swap`.
+   When you are finished, the Unknown list should go away, and all three mount points should be assigned. Proceed normally with the installation from there.
