+These errors occur during partition analysis and validation, and can be caused by the presence of multiple system partitions. For example, if you installed a new system drive but left the previous system drive connected, this can cause a conflict. To resolve the errors, disconnect or temporarily disable drives that contain the unused system partition. You can reconnect the drive after the upgrade has completed. Alternatively, you can delete the unused system partition.
