I installed a new/larger (4TB) hard drive on my computer. I have Windows 7 installed on the old drive (1TB) and using backup of the drive with a system image, I restored that to the new drive. All seems to work fine.
Now I want to extend the partition on the new drive. In Disk Management, I can see the unallocated disk space next to the allocated C: drive. There are no logical partitions, just the allocated and unallocated sections. When I right click to extend the C: drive, the "Extend" option is disabled.
Why would it be disabled and is there a way for me to enable it?
I found some posts that says it has to be converted to be a dynamic disk first, but this option is also disabled.
