Migrate Windows 11/10 to M.2 SSD without Reinstalling (2023)

What is M.2 SSD?

Before learning how to migrate Windows 11 or Windows 10 to M.2 SSD, you may want to know more about this type of SSD.

An M.2 SSD, originally known as the Next-Generation Form Factor (NGFF), is a solid-state drive that conforms to a computer industry specification written for internally mounted storage expansion cards of a small form factor.Like many other SSDs, M.2 SSDs have shorter boot up time, lower power consumption and less noise than HDDs.

The advantages of M.2 SSD are the reasonswhy people copy HDD to M.2 SSD.Some Windows users still wonder if they could use M.2 SSD as a boot drive. Actually, the answer is yes.

๐Ÿ’™M.2 vs. SATA SSD for boot drive, which is better?

An M.2 SSDtakes up less room than 2.5-inch SSD. What's more, an M.2 SSD usually uses NVMe protocol (PCI-e), so it is generally faster than a SATA SSD that uses AHCI protocol. As a result, there's a growing need tomigrate Windows 10/11 to M.2 SSD nowadays.

๐Ÿ’™Would a 250GB M.2 SSD be sufficient purely for OS storage?

Actually, for Windows OS installation and all other basic applications, a 128GB SSD would be enough. To leave more space for future use, 250GB is also a good choice.

How to transfer Windows 10/11 from HDD to M.2 SSD

Generally, there are two ways of moving Windows 10/11 from HDD to M.2 SSD. You can either use Windows built-in tool or a third party disk cloning tool. Either way you choose, you need to do some preparations first:

โ—† Clean up your old hard drive. Delete unwanted files, uninstall unnecessary apps, perform a disk cleanup, etc.
โ—† Install M.2 SSD properly. Make sure your desktop or laptop'smotherboardhas M.2 slots, and insert the M.2 SSD into it.

Next, I will walk you through the detailed steps of each way.

  • Way 1. Transfer Windows 10/11 to M.2 SSD (Windows tool)
  • Way 2. Clone Windows 10/11 to M.2 SSD (Easier)

Way 1. Transfer Windows 10/11 to M.2 SSD (Windows tool)

Here you will use built-in tool tocreate a system backup and thenrestore it on SSD with the help of an installation disc. Now, go through all the detailed steps in the following:

2. Select an external hard driveas destination place to save your backup.

3. The system drive and system reserved drive are included by default. Click Next to continue.

4. Confirm the settings and click Start Backup.

Step 2. Create installation media

After creating a system image in Windows 10, you can easily migrate OS to M.2 SSD. The process requires an installation disc for boot. Pleasedownload Windows 10 Media Creation toolon the Microsoft software download page and create a bootable USB with it.

That is the way of transferring Windows from HDD to M.2 SSD. Obviously, the operation steps are a little bit troublesome, and it is error-prone for users who have less computer knowledge and skills.In a few cases, you may encounter the error Windows 10 backup not working.

To make things easier, it is recommended to try the second way, migrate Windows 11/10 with M.2 SSD cloner. It has a user-friendly interface and is popular among Windows users.
