In such case, AOMEI Dynamic Disk Manager is your best choice.

Note: In order to extend system partition on dynamic volume, there must be some adjacent unallocated space. AOMEI Dynamic Disk Manager provides two methods to generate adjacent unallocated space for system volume.

How to generate adjacent unallocated space for system volume?

As a full-featured software, AOMEI Dynamic Disk Manager provides two methods to generate adjacent unallocated space:

>Method 1: Take free space from other volumes

This method applies to the situation when there is enough free space on the same disk.

Step1: Right-click volume D and select "Shrink Volume".

Step3: After completing the steps above, there is some adjacent unallocated space behind system volume. Now, you can right-click C drive and select "Resize/Move Volume" to extend system volume on dynamic disk. Do not forget to click "Commit".

>Method 2: Move other volumes to another disk.

This method is very useful and convenient when other volumes are also full, namely, there is no free space on the same disk. However, this method is available when there is unallocated space on other disk, besides, the unallocated space must be equal or larger than the volume you move.

Step1: Select volume D. Then, click "Move Volume Slice Wizard".

Step4: Select the destination disk.

Step5: After completing the steps above, you will preview that the volume D has been moved to Disk 4 and an adjacent unallocated space has been generated. Now, you can right-click C drive and select "Resize/Move Volume" to extend dynamic system volume. Do remember to click "Commit".

Apart from extending dynamic system volume, AOMEI Dynamic Disk Manager also enables you to increase striped volume, enlarge mirrored volume, expand RAID-5 volume, convert dynamic disk to basic, convert GPT disk to MBR, etc.
