Windows Server 2012 R2 Standard

i am recovering an Exchange 2013 Mailbox server and have reformatted this Windows Server 2012 R2. when i restart the cluster service is disabled. if i enable it and start it, it gives those errors in event viewer as 1090:

Description:
The Cluster service cannot be started. An attempt to read configuration data from the Windows registry failed with error '2'. Please use the Failover Cluster Management snap-in to ensure that this machine is a member of a cluster. If you intend to add this machine to an existing cluster use the Add Node Wizard. Alternatively, if this machine has been configured as a member of a cluster, it will be necessary to restore the missing configuration data that is necessary for the Cluster Service to identify that it is a member of a cluster. Perform a System State Restore of this machine in order to restore the configuration data.

and 7024:

The Cluster Service service terminated with the following service-specific error:

i would have tried the system state restore but there is no system state backup for this particular server.

how does one recover a cluster member then?

if this may help, in the GUI add roles wizard, failveover clustering is not showing up. i added it using powershell.

i reinstaller failover-cluster and management tools. i noticed in event viewer error 2051:
