Question: I’m absolutely blown away by how impossible this task appearing to be. I’ve been through probably a hundred separate Google search results, every single one explaining how to “right click the volume and click extend”. Well guess what, the extend button is greyed out. Here’s a screenshot of Disk Management:
I can’t use the Windows snipping tool with a context menu open (and my keyboard lacks a print screen button), but believe me when I say that the extend button is greyed out when right clicking the Windows 8 partition. I’ve tried using DISKPART.exe too:
Would anybody care to fill me in on why Windows is refusing to extend the partition? What will I have to do in order to extend the partition with the remaining 140GB on the drive?
Answer: Windows 7 “Extend” feature works only if the unallocated size is to the right. Yours is to the left. You will need to use a 3rd party partition application (PartedMagic/GParted).
Before messing around with partitions, backup everything first.
