"After installing Windows 10, we need to partition hard drive in Disk Management to distribute more free space for Windows 10 future use. How to partition hard drive in disk management? Can we partition it without data loss? I heard that you had to format hard drive to create new volume, can we do partition it without data loss? "
If you have unallocated space on your hard drive, it's ok to create partition with it without data loss, but if you have no such space available, you have to split exist partition into partitions, in Windows 10 Disk Management, Delete Volume is the function you shall use, which will not keep data when operating. We'll guide you how to do it without data loss in this page.
Steps of creating a new partition in Windows 10 Disk Management:
When a new window pops up, it means you succeed, this window is file explorer of the volume you created.
Now you have unallocated space in primary partition now, or free space in extended partition.
Windows 10 Disk Management has no function called Merge Partitions, but we simulate it in Disk Management, without the help of any third-party partition software, the thoery is to maunally copy everything from one partition to another, delete one partition, merge the free space to another
Functions we’ll be using to merge partitions:
Steps of merging volume using Disk Management:
By doing so, we can merge two partitions in Disk Management
What’s the problem with method?

We can create VHD file in a partition and attach it to the disk map in Disk Management, since the VHD drive is also treated as a file in File Explorer, it can be moved, cut and pasted to other drives, say if we’d like to move it from E Drive to D Drive, simply cut and pasted it to D Drive, attach this file again to list it in disk map, although it’s still a new drive in File Explorer and Disk Management (even with the same drive letter), free space in E Drive is increased
Another way to partition hard drive in Windows 10 is to use command prompt: diskpart. Here are the steps to create volume using command prompt, along with shrink partition and extend volume in Windows 10 CMD
> list disk > sel disk 1 > list partition > sel partition 1 > ass > exit
> list disk > sel disk 1 > list partition > sel partition 1 > shrink > or shrink desired=20480 > exit
shrinkdirectly will autmoatically shrink partition by Windows, you can also type
shrink desired=***to define your own partition size.
Manager partitions in Disk management or command prompt : diskpart can keep data intact on the operation of create and shrink volume, but not extend volume when the free space or unallocated space is not next to the partition you want to extend, for example, you want to extend C Drive, the system partition, but free space is right behind E partition, then Extend Volume gray out in right-click menu or C Drive, there's no way to make this function active but to delete D partition, the partition next to C Drive, and make D partition as continues unallocated space to C Drive. So we shall try another system utility to perform the same step without data loss.
Partition Hard Drive in Partition Expert is easier than in Disk Management or Command Prompt diskpart. You can keep data safe no matter you are creating, shrinking or extending partitions.
