Note:
Before you get into the solutions, please make sure that you have made a backup of all the files on your partitions as one or two solutions might require you to delete a partition.

You can also get some unallocated space by shrinking a partition if you want to avoid deleting it completely. However, it is important to note that if the unallocated space and the volume you want to extend aren’t right next to each other, you still won’t be able to extend the volume.
