You can't change the partition Windows is running from in that same Windows.
Free alternatives are:
- GPARTED in any Linux distro
- GPARTED on it's own dedicated disc
- running Windows to go from a stick
- running Windows from another disk on your PC (temporary install)
I recently added another drive to my PC which then made the D: drive partition redundant. The drive which has C: drive partition also ONLY has D: drive partition.
I formatted D: drive and then did a volume SHRINK VOLUME to the minimum size. I then ended up with UNALLOCATED SPACE.
I then tried to EXTEND C: drive but it is greyed out - I cannot select it.
Can I use Windows 7 Disk Management tool (if so how) or can only a 3rd party disk management application work for me? If so please advise if any freeware.
