I have AWS EC2 WS\2012R2 Instance w\EBS Volumes. I was able to successfully Modify (ADD Space) in AWS. When I RDP to instance and R-Click on volume the Extend Volume option in greyed out. I have attempted NUBI Partitioner (free) & AOMEI Partition Assistant (free) but both failed to install on OS. Not sure how to resolve this issue any help is much appreciated.
