“Can I clone only Windows partition to SSD?”

“I have used my computer for years and now it worked slowly. Thus, I am planning to get a new 1TB SSD to replace the old only 100GB HDD with Windows 10 installed in order to improve booting speed and performance of my computer. But I just want to keep the Windows partition, not all partitions on the original HDD. So I was wondering can I just clone Windows partition to my new SSD I am getting. If the answer is “yes”, how should I do to fulfill this task?”

Try the best Windows cloning software

When your system is running slowly on the traditional hard drive, it is always a great idea to clone Windows partition to a faster SSD drive. But, how can you perform this special cloning task?

The most effective and easiest way is to adopt a professional disk or partition cloning software such as AOMEI Partition Assistant Professional. This software comes with the following amazing features:

  • “Migrate OS to SSD”designed for users to migrate or clone only OS partition from to SSD or HDD. And you can boot from the cloned disk after the cloning completion.

  • It supports migrating only OS partition from MBR to MBR, GPT to GPT, GPT to MBR as well as MBR to GPT.

  • It can also help you align SSD partition to improve the reading and writing performance of the destination disk.

Furthermore, AOMEI Partition Assistant also provides users with “Disk Copy” and “Partition Copy”. The former allows you to copy whole disk to another hard drive without reinstalling everything, while the latter one is perfect for copying data partition to another disk.

Steps to clone Windows Partition to SSD/HDD via AOMEI Partition Assistant

Now, let’s take a look at how to clone system/boot drive to another hard drive via AOMEI Partition Assistant.

Warning: this process will require you to delete all existing partitions on the destination hard drive, so please back up important data in advance.

Step 1. Install and run AOMEI Partition Assistant. Choose “Migrate OS to SSD” in the left panel and click “Next”.

Step 4. Then a note about how to boot OS from SSD/HDD will pop out, read it and click “Finish”.


Step 5. Back to the main interface, click “Apply” on the right top corner to commit the operation.


After the OS partition migration is done, you can replace the old hard drive with the new disk, enter BIOS to change the boot order (make the new hard drive in the first place), then you can boot computer from the cloned disk successfully.

Note: If you clone/migrate OS from MBR to GPT disk, you need to change BIOS boot mode to UEFI, the vice is also true.

Further reading: clone Windows partition to USB

From the Google search results, we can know some users want to clone Windows partition to USB flash drive (rather than SSD drive) in order to make a portable Windows USB drive, which they can carry around easily and run the familiar operating system on other computers. Luckily, AOMEI Partition Assistant Professional also can meet such requirements thanks to its “Windows To Go Creator”.

Similar to the “Windows To Go” developed by Microsoft, but it is much more advanced. Windows native “Windows To Go” can only work on Windows 10 Education/Enterprise/Pro and Windows 8/8.1 Enterprise, and it requires the corresponding Windows ISO files and an over 32GB certified USB drive.

By contrast, “Windows To Go Creator” from AOMEI Partition Assistant can work on all editions of Windows 10/8/7. Non-certified USB drive is also OK as long as it is at least 13GB. Moreover, if you don’t have Windows ISO files available and don’t want to download one, you can even use this function to create Windows To Go USB with current system.
