How to Resize SSD Partition in Windows 10: Easy Guide

Can You Resize an SSD Partition?

Yes. You can resize an SSD partition in Windows 10 without reinstalling Windows in many cases. A partition manager such as MiniTool Partition Wizard can resize or extend an SSD partition by using available free space or unallocated space.

Windows Disk Management can also extend a partition, but the unallocated space must be directly adjacent to the partition you want to extend.

The following two methods show how to resize an SSD partition. The first method uses MiniTool Partition Wizard, while the second uses Windows Disk Management.

Method 1: Resize SSD Partition with MiniTool Partition Wizard

If your SSD system partition is running out of space, you can use MiniTool Partition Wizard to extend it by taking free space from another partition or unallocated space on the same SSD. This method is especially useful when the available free space is not directly next to the target partition.

Here, I take resizing system partition as an example. To run MiniTool Partition Wizard Bootable Edition, firstly, you need to create a bootable USB drive by using MiniTool Partition Wizard’s Bootable Media Builder.

Step 1. Prepare a USB flash drive (or CD/DVD disc) and connect it to a normal computer.

Step 2. Get MiniTool Partition Wizard Pro Edition by clicking the following button. Install it on your computer and get it registered.

Step 3. At its main interface, launch Bootable Media Builder (you may see this feature by clicking the More Tools icon).

Step 4. Select WinPE-based media with MiniTool plug-in to continue.

Step 5. Select USB Flash Drive option and choose the correct USB flash drive. Then click Yes to confirm that you want to burn the boot flash drive.

Step 6. When you select the USB Flash Disk, please make sure the USB does not contain any important files and data as MiniTool Partition Wizard will format the drive firstly. Then click Yes to go on.

Step 7. Click Finish after successful burning.

Step 8. Enter the BIOS to change the boot order, giving the USB device boot sequence priority over the hard drive. If you are using a DVD/CD disc, change the boot sequence priority accordingly.

Step 9. When you boot from the USB drive, you will get the interface of MiniTool PE loader, then click MiniTool Partition Wizard to get the main interface of MiniTool Partition Wizard Bootable Edition.

Step 10. On this page, all disks and partitions are shown. To extend system partition, you need to select it and choose Extend Partition.

Step 11. Now, you can choose an existing partition or unallocated space on the same SSD disk to take free space, which will be used to extend the target system partition, and then drag sliding handle to decide how much free space to take. After that, click OK button to go back to the main interface.

Step 12. In this interface, as long as you click Apply button, all previous changes will be applied to computer. That is to say SSD partition resizing will be completed after application.

This is how I resize SSD Windows 10. Nevertheless, resizing SSD partition may cause the very partition unaligned, which will slow down SSD read-write speed or even computer running speed. Therefore, it is recommended to align SSD partitions with MiniTool Partition Wizard after SSD partition resizing.

Method 2: Resize SSD Partition with Disk Management

Windows Disk Management can resize an SSD partition without installing third-party software. However, it can extend a partition only when suitable unallocated space is directly adjacent to it. If the Extend Volume option is unavailable, you may need to use another partition management method.

Step 1. Open Disk Management.

Press Win + X and select Disk Management from the menu.

Step 2. Find the SSD partition.

Find the SSD containing the partition you want to resize. Check whether there is unallocated space directly to the right of the target partition.

Step 3. Choose Extend Volume.

Right-click the target partition and select Extend Volume.

Step 4. Specify the amount of space.

In the Extend Volume Wizard, click Next, select the amount of unallocated space you want to use, and click Next.

Step 5. Complete the operation.

Review the settings and click Finish. Windows Disk Management will extend the partition using the selected unallocated space.

Important: If Extend Volume is grayed out in Disk Management, check whether the unallocated space is directly adjacent to the target partition. Windows Disk Management generally cannot move partitions to make separated unallocated space available for extension. In this situation, you can use MiniTool Partition Wizard to resize the SSD partition instead.

Bottom Line

SSD partition resizing allows you to extend a system partition without reinstalling Windows. MiniTool Partition Wizard offers a flexible way to use free space from another partition or unallocated space.

Windows Disk Management can also extend an SSD partition if the required unallocated space is directly adjacent. Choose the method that suits your needs for resizing or extending your SSD partition.
