Turn free space into unallocated space

[decipherfreak]

I was trying to make some unallocated space to create a new partition (want to try out new os) and used the shrink option in disk management. It created some free space but is still part of the partition. How, can I get some unallocated space instead?
Thanks

Strange.
Try GParted LiveCD.

How full is the partition you are trying to shrink?
