I have 136Gb of unallocated space that cannot be utilized.
When i right click on the unallocated space in disk manager all options are greyed out except "New Simple Volume" When i attempt to create the new volume the error above happens, see attached image
I have tried everything from Partition Magic to Mini Tool Partition Wizard to either create a new volume or expand the space.
This problem arose after I created a dual boot with XP and Windows 7. After was happy with Win7 I decided to remove XP but i have been left with an active XP partition and the unallocated space
Any ideas to remove the XP partition and reuse the unallocated space?
