so far i’ve tried to…
Use Disk Management -
Step 1: Click on the Start menu and browse for your Computer icon
Step 2: Use your mouse to right-click on the icon and choose Manage from the displayed list
Step 3: Choose Continue if the UAC pops up.
Step 4: Select the Storage category in the left pane and open Disk Management
Step 5: A window will list your disk partitions and to alter them, use your mouse to right-click on the partition that you have to change.
Step 6: From the drop down list, select either to Extend or Shrink: the volume of the chosen partition

…what i found is that the “Extend” option was grayed out!

so, what might i try next?
