Windows 10: Merge partitions without damage ?

How do I merge these three partitions without damaging windows from booting.

Merging System Partition with a Large HDD

There is plenty of third party software available on the Web that will do that for you, but I find the free version of AOMEI Partition Assistant the quickest and most intuitive way to manage partitions without data loss -

Honestly, I would shrink the data partition and extend the System partition to something in the region of 100GB+

Merging partitions can be done without data loss, however the operation is not without its pitfalls as the location of data is changed from D to C for example and this can cause problems . . .

Hi,

Welcome to Microsoft Community.

I understand that you have a question in merging the partition.

I would like to inform you that you have an option of merging the drives with simple changes from the issue description. Do not merge the EFI system partition as it deals with the boot process. Also I suggest you reserve a drive so that you can retrieve
files of Windows 10 when needed.

Create a recovery drive

Now you can merge four drives out of six.
To do so refer the steps below.

• 
  You can do that by right clicking on the drive.
  
• 
  Select Expand and follow the on screen instruction.
  

Hope this information helps you.
