I was installing SQL Server 2008 R2 on a single-node cluster and accidentally installed into the wrong shared disk on the SAN.
But when I tried to use the 'Remove node' from the installation centre after the rule checks I got stuck at the 'Cluster Node Configuration' page. I have 4 instances running on the single node and none of it is shown in the 'SQL Server instance name:' drop-down list. Therefore I could not remove the instance I wanted to remove.
Anyone had similar issue before? I am running Windows 2008 R2 SP1 + SQL Server 2008 R2 SP2(slipstreamed).
