Reason for transferring Windows 10 to SSD

“Hi guys, I’m willing to migrate Windows 10 from HDD to SSD recently, but I have no idea of steps. Can anyone tell me how to transfer Windows 10 from HDD to SSD without losing data? Thanks in advance.” This is a kind of questions commonly seen among a lot of forums.

Well, as the reading and writing speed of SSD is much faster than that of traditional HDD, it improves the overall performance of the system, which takes less time to boot from the SSD. Besides, more and more people can afford to buy an SSD, so migrate Windows 10 from HDD to SSD becomes universal.

Can I transfer Windows 10 with built-in tool?

Although a built-in tool in Windows 10 can help you create a system image, there are some limitations.

If your SSD capacity is smaller than the current HDD, you need to shrink volume in Disk Management first in order to fit a SSD. Then you can create a system image. After finishing a kind of settings through that wizard, you’ll be asked whether to create a system repair disc or not. One important thing is that the process could fail at last if the shrunken partition still not small enough. In this case, you have to go back to the first step again! So, another much easier way is recommended.

Clone Windows 10 from HDD to SSD safely and easily
