Remove Windows FCI completely When I built the cluster I forgot to uncheck the storage. It's now giving me all sorts of errors. How can completely remove the cluster so I can rebuild it? 
This is a 3 node cluster and I evicted two nodes, but when I try to evict the last node I get:



I removed all the Disk and Pools from the remaining node. 
Can you please guide me
In Failover Cluster Manager, right-click on the cluster, select More Actions, and click on Destroy Cluster.
