So heres the deal. I deleted the Ubuntu 10.04 partition in windows computer management/disk management. Then i shut down the computer, upon booting up i was greeted with an grub error and unable to boot into windows. I used super grub disk, now windows boots up fine now. I'm left with this now, three other partitions and a 218gb of free space. How can i allocate my free space (218gb) to my C: drive? I right click my C: drive but the extend volume is grayed out. Only the Shrink volume is selectable.
