When move boot partition in Windows 10?

Basically, you may want to move system boot partition under the following two cases.

☞ Case 1: Improve computer performance: Your PC might be running slowly and you want to move Windows 10 boot partition to another drive like SSD for a faster speed. Take the following scenario as an example:

“I want to clone boot partition (C:) of an HDD with 3 partitions (Docs, etc. on these), and clone it to an SSD drive that will be my boot drive with all my programs. I assume this will speed but my PC. The SDD is 96Gb, and the C:/partition is 98GB, but only 40Gb is used, so there is plenty of space. So far I can only find software to clone a whole HDD, not a partition.”

☞ Case 2: Extend partition. When partition C running out of space, the running speed of your PC can be slow down and you can receive low disk space warning. To solve the problem, the first idea that occurs to you is extending partition. But when there is no unallocated space right behind the to-be-managed partition, you need to move partition which is not allocated. Take the situation given below for example:

“My C drive is running out of space and it's becoming a problem. It has 90 something GB on the C partition and my hard drive has some 300 GB of unallocated space. I know how I can expand the C volume, but it isn’t next to any unallocated space. Is there a way to move the volume next to the unallocated space to expand it, or vice versa”

Move boot partition to another drive without Windows reinstallation

If you want to move system boot partition to another drive, like new SSD or larger HDD, AOMEI Partition Assistant Professional can provide help. It can clone all OS related partitions to another drive with built-in function Migrate OS to SSD, which ensures that you boot from the new drive after moving. Now, check out how to move Windows-related partitions (such as system reserved partition, partition C) in Windows 10 using AOMEI Partition Assistant Professional.

Step 1. Click “Migrate OS to SSD” and click “Next” in the pop-out window.

Step 2. Select an unallocated space on the destination SSD and click “Next”.

Step 3. In this window, you can resize the partition. Then, click “Next”.

Step 4. A note about how to boot OS from SSD or HDD will appear. Read it and click "Finish".

Step 5. Click Apply and Proceed to commit the operation.

✍ Notes:
◆If you want to move only certain specific data partition to a new drive, you can right-click it, choose Clone Partition and follow the prompts.
◆ The data on the destination location will be covered by the source data, so data backup on the destination drive is very important.
◆ You can also use AOMEI Partition to move Windows 7/8/8.1 to another drive as well. If you need to move Windows Server 2019/2016/2012/2008 to a new drive, please employ AOMEI Partition Assistant Server.

Move partition to extend space

When you want to extend partition C but the unallocated space is behind D drive, you can move partition D (partition D is behind partition C) to make the unallocated space contiguous behind C drive. If there is no unallocated space on your hard disk, you can shrink partition with enough space. Now, check out how to resize and move partition, so that you can extend C drive.

Step 1. Run AOMEI Partition Assistant Professional. In the main interface, right-click partition D and choose Resize Partition.

Resize D Partition

Step 2. Put the mouse on the left side of D partition and drag it rightward until the unallocated space reaches your need. Then, click OK.

Shrink D Partition

Step 3. Put the mouse on the selected partition and drag it rightward when the mouse become a cross crux, then click OK.

Move D Partition To Right Side

Step 4. Click Apply and Proceed to commit operation.

Then, you'll get unallocated space adjacent behind C drive and you can increase the partition size of it.


When you meet these two cases, do not worry！AOMEI Partition Assistant Professional can help you to move boot partition windows 10 to another drive or to extend partition. The software also allows you to convert dynamic disk into basic without data loss, split partition and so on.
