Okay this is annoying!
I have a C: drive that is the primary partition (bootable) that I would like to extend. In order to do that it seems like I need to have Unallocated Space to the right of the partition.
Right now, I have "Free Space" to the right. How in the world do I make it Unallocated (not formatted)?
There must be some command line utility to be able to do this.
