When trying to restore a virtual machine back to it's source, the only option is shown: 'Do not restore'.
When Recovery Point, Restore was used, Live Recovery (Recover to a protected machine) was selected. This option requires already running OS with agent software installed on it and obviously cannot be used to restore OS-related volumes. Only data volumes can be restored that way.
To restore OS volumes, please use either Bare Metal Recovery (BMR) process (https://support.quest.com/technical-documents/rapid-recovery/6.2.1/user-guide/78#TOPIC-982590)
Or, if target machine is a virtual machine, use a Virtual Export procedure (https://support.quest.com/technical-documents/rapid-recovery/6.2.1/user-guide/67#TOPIC-982549)
