How to Use Disk Management in Windows 10
Since we already know about Disk Management, then, we will talk about how to use it to solve the real problem. Most Windows 10 desktop and laptop users have encountered the problem of low disk space warning, especially for the system partition. To solve such kind of problems, extending volume would be the most effective way.
Some users may want to create a new partition since now most disk only has a big C drive. In this part, we'll show you how to extend volume and how to shrink the volume to create a new drive.
1. Extend C drive via Disk Management with adjacent unallocated space
If there is an adjacent unallocated space behind C drive, you can extend it in Disk Management. Here are detailed steps:
Step 1. Press Windows + R at the same time to open Run dialogue.
Step 2. Input diskmgmt.msc and hit Enter to open Disk Management.
Step 3. Right-click C drive and choose "Extend Volume".
Step 4. Follow the prompts that will appear to complete this operation.
Note: If the Extend Volume greyed out and cannot be clickable, the reason is that the function of Extend Volume in Windows 10 is only available when there is contiguous unallocated space behind the partition you would like to extend.
2. Create a new partition in Disk Management from C drive
To use Disk Management to create a partition from C drive, you need to create unallocated space first, and then create a new partition based on it.
Step 1. Press the "Windows + X" and select "Disk Management" from the menu.
Step 2. Locate the C drive in the list of available disks and right-click it.
Step 3. Select "Shrink Volume" from the context menu that appears.
Step 4. In the Shrink window, enter the amount of space you want to allocate to the new partition in megabytes (MB), then click "Shrink".
Step 5. Once Disk Management has completed the shrinking process, you'll see a black area labeled "Unallocated."
Step 6. Right-click the unallocated space and select "New Simple Volume" from the context menu that appears.
Step 7. Follow the prompts in the New Simple Volume Wizard to assign a drive letter, format the new partition, and complete the creation process.
Is it easy? Yes, and using Disk Management to initialize disk, delete volume, and format volume is as same easy as extend volume-Select the disk or partition-> right click it-> choose the operation you want to execute and follow the hints step by step.
But, what can you do when you don't have unallocated space or adjacent space on hard drive?
If you insist on enlarging the partition via Disk Management, but there is no contiguous unallocated space, the only solution is to delete the partition behind the to-be-extended volume, and then add the generated unallocated space into the target volume using the "Extend Volume". You may meet other problems, such as “shrink volume greyed out”, “the disk is not showing up in Disk Management”, “cannot initialize the disk”, and so on.
What should you do when those bad things happen?
Better one-in-all disk manager for Windows 10
Windows 10 Disk Management is a good utility for Windows users. But it does have a lot of limits. Thus, we’re looking for a better disk manager, and here we recommend- AOMEI Partition Assistant Standard, a powerful and free disk management tool that can totally fix the shortages of the built-in disk partition manager in Windows 10. It is compatible with Windows XP, Vista, 7, 8, 10, 11.
For example, AOMEI Partition Assistant allows you to extend partition whether or not there is unallocated space right behind the extended partition in Windows. As only as there is unallocated space adjacent to the partition, no matter if it is on the left side, or right side, the Resize/Move Partition of AOMEI Partition Assistant can help you enlarge the partition with the unallocated space. What's more, you can even use AOMEI Partition Assistant to enlarge a partition without unallocated space on the hard drive.
The following contents will show you how to extend partition successfully with this disk manager in Windows 10 within two different situations.
▶ Case 1: Extend partition when there is non-contiguous unallocated space [FREE]
In this situation, we recommend the "Merge Partitions" of AOMEI Partition Assistant, which can combine two adjacent partitions or non-contiguous unallocated space into another existing partition.
Before you do:✎...
You can merge one or more parts of unallocated space into a partition.
The" System Reserved" partition could not be merged.
If there are running applications in the partition you are going to operate, AOMEI Partition Assistant will suggest you close them or perform the operation under PreOS Mode.
If there is no unallocated space on the disk, please go to Case 2.
Step 1. Download and launch AOMEI Partition Assistant Standard.
Step 2. Right-click on the partition you need to extend (e.g. D Drive) and choose Advanced > Merge Partitions.
Step 3. Tick the checkbox before the unallocated space and then click OK.
Step 4. Now you can preview the unallocated space that has been added to C drive. To save the change, please click Apply button in the top left corner.
▶ Case 2: Extend partition when there is no unallocated space [Advanced]
When there is not any unallocated space on the disk, you can try the "Allocate Free Space" instead to directly move some free space from one partition to another.
Before you do:✎...
If there are 4 primary partitions on an MBR disk, and you want to split one of them, the partition that is being split will be converted to a logical partition automatically.
If one disk has four primary partitions, the program would not allow you to split the system partition or boot partition, unless you could convert one of the other partitions from primary to logical partition, and then the program will allow you to split the system partition. The newly generated partition will be automatically set as a logical partition.
