How to migrate only Windows 10 to SSD?

"Hi, I just got a new SSD, and I want to move my Windows 10 and only my OS over to it as there is not enough space on the SSD. If anyone can give me a step by step guide to it, that would be great. My PC info: Windows 10 64bit, the SSD is 120GB."

Why Migrate Windows 10 to SSD

More and more users are installing or moving Windows OS on SSD, and you can see reasons below.

Advantages of Using SSD as Startup Disk

  • Faster boot speed. SSD usually takes about 20 seconds to start the system.
  • SSD starts the software especially fast. Especially for games, PS, and similar large software.
  • You can use SSD as the system disk that is separated from the data disk. If the system crashes, no data will be lost.
  • SSD does not produce noise. It is not afraid of vibration and impact.

Why Choose OS Migration Instead of Reinstalling

Installing an SSD as the system disk is one of the common ways to upgrade a computer. However, it is very time-consuming and troublesome to perform fresh Windows and program installations once again. And data saved on C drive will be lost. So, migrating OS to SSD is the best way.
