We are running a server with a couple Hyper-V VMs. When I created one of the VM I allocated too small of a space to the OS partition thinking I can Expand it later........ Seems I was wrong! Extend Partition is not an option for the C: Partition.
I tried moving the Page File to the D: Partition and still could not Extend C:.
I downloaded EaseUS Partition Master and tried using it without success.
The VM Drive is a MBR type running 2012 Server R2 and when I created the VM I did a Gen1, IDE Drive, if that info helps.
I attached a screen shot for Disk Management.
Thanks for you help!
