Windows 10: How to use unallocated space left in between partitions in dual boot

The 300GB partition is for Ubuntu 20.04 with dual boot with windows 10.

I want to combine both unallocated partitions to create a separate partition

I got to know that windows disk management tool is not capable of doing it and I should use AOMEI assistant for it, But the problem is AOMEI assistant is showing my ubuntu partition as empty and combines it with the unallocated 189GB partition resulting in 489GB unallocated partition.




Is there any other method or tool which can solve my problem?

Partition space

You're not understanding this. Unallocated space is NOT equal as (partitioned) empty space.

Unallocated space means empty RAW sectors on HDD. Empty space means an already allocated file system (either FAT32 or NTFS or any other) that is not occupied by any data.

So in your case, as DanTheBanjoman already suggested, don't try to shrink "unallocated space", extend the main (C*Smile partition instead. You can't shrink something that doesn't exist (unallocated space), but you can extend the existing partition over unallocated space.
So, just select the C: partition and extend it further. Program should automatically allow you to do that. I'm not using Partition Magic, but i usually done this with either:
MiniTool Partition Wizard Free - manage and resize disk partitions (also for 64bit OS!)

or

EaseUS Partition Master - manage disk partitions (only for 32bit OS!)

Was commenting on the pic in post #21. Not suggesting anything. It just looked like the step you were doing was incomplete.
