I have these partitions:
I want to merge D and G together, but I can't. D can merge with C, but G cannot merge with anything. Why is this? I recently installed Windows again, before I had 750GB main partition and 250GB data partition, then during the windows install, I resized the 750GB to 500GB and therefore around ~187GB was left unused, but now I can't merge that 187GB with anything!
