Not able to select the disk during Oracle 11g Installation Hi All, During the 11g installation on Win 2012, I am not able to select the available disks which are already stamped using ASM. Any idea what could be the reason? I have tried to select using keyboard space as well but doesn't work out. Appreciate your help. Thanks.
You should check if it is not a ownership issue. The disks should be owned by Oracle. 

A common workaround to this issue is to delete and recreate the disks from scratch.
